Lee la siguiente transcripción de una entrevista radial y responde la pregunta.

Entrevistadora: Bienvenidos a 'Letras de Hoy'. Hoy nos acompaña el aclamado novelista, Diego San Martín. Diego, la inteligencia artificial está revolucionando la forma en que estructuramos las narrativas. Muchos colegas tuyos ya la utilizan para superar el bloqueo del escritor. ¿No crees que estamos ante el amanecer de una nueva era dorada para la literatura?

Diego: Hola, Laura. A ver... 'dorada' es un adjetivo bastante generoso. Es innegable que estas herramientas procesan datos a una velocidad asombrosa y pueden generar tramas predecibles que satisfacen al mercado de consumo rápido. Si tu objetivo es ensamblar un producto comercial en un fin de semana, felicidades, tienes el aliado perfecto. Sin embargo, la literatura, la que perdura y nos confronta con nuestra propia humanidad, se nutre de la duda, del error y de la vulnerabilidad del autor. Esa fricción íntima con el lenguaje es algo que un algoritmo, por ahora, solo puede imitar de manera cosmética. No es que rechace la tecnología, simplemente me niego a confundir eficiencia con arte.

¿Cuál de las siguientes afirmaciones describe mejor la actitud de Diego San Martín frente al uso de la inteligencia artificial en la creación literaria?

Show answer & explanation

Answer: Reconoce su utilidad práctica para fines comerciales, pero cuestiona su capacidad para generar obras con verdadera profundidad humana.

Answer

The correct answer states that the author recognizes the practical utility of AI for commercial purposes, but questions its capacity to generate works with true human depth.
The correct answer accurately reflects the two distinct parts of the speaker's argument. First, he admits the technology is a 'perfect ally' if the goal is to quickly assemble a commercial product (recognizing practical utility). Second, he contrasts this with enduring literature, arguing that algorithms lack the genuine human doubt and vulnerability required for true art, only being able to imitate it cosmetically (questioning its capacity for human depth).

An excerpt from the civic innovation podcast *MetroPulse* features correspondent Sofia Morales discussing the deployment of autonomous urban delivery corridors:

'When the municipal transport authority initially authorized automated logistics drones across high-density residential districts, neighborhood associations immediately raised acute concerns regarding ambient noise, structural safety, and privacy. Preliminary test flights further exposed severe navigation bottlenecks during evening peak hours, causing frequent distribution delays and public skepticism. Rather than abandoning the automated fleet entirely, project engineers decided to smooth the rough edges of the underlying routing system. By recalibrating altitude thresholds, adjusting propulsion frequencies, and dynamically rerouting flight paths away from residential courtyards, transit officials successfully resolved early operational flaws and reduced community noise complaints by forty percent. What began as a contentious trial has ultimately yielded a reliable blueprint for modern metropolitan distribution.'

During a recorded discussion on urban ecology, soundscape researcher Professor Joaquín Serrano answers an inquiry regarding urban acoustic management:

Camila: "Many municipal planners view ambient city soundscapes as unavoidable noise pollution that should merely be suppressed with physical acoustic barriers. How do you evaluate that approach in light of your bioacoustic mapping project?"

Professor Serrano: "Treating urban acoustics solely as a nuisance to muffle overlooks the vital ecological information embedded in sound. While conventional barriers address volume, they often create sterile acoustic dead zones. Our recordings show that when cities intentionally cultivate micro-habitats with running water and native vegetation, the resulting natural soundscape naturally masks traffic rumble while restoring biological connectivity. It is not about silencing the city, but about reintroducing living frequencies."

Which of the following best characterizes Professor Serrano's attitude toward conventional municipal noise control methods?

Show answer & explanation

Answer: He considers them an oversimplified strategy that creates sterile environments instead of cultivating natural auditory vitality.

Answer

Professor Serrano considers conventional noise control methods an oversimplified strategy that creates sterile environments instead of cultivating natural auditory vitality.
The interviewee explicitly critiques standard acoustic barriers for producing 'sterile acoustic dead zones' and failing to account for the ecological value of ambient sound. Rather than pursuing absolute silence through physical suppression, he advocates for cultivating micro-habitats that introduce natural frequencies to mask mechanical noise.

Show answer & explanation

Answer: To directly identify and confront the most critical, sensitive root causes of a systemic problem

Answer

To directly identify and confront the most critical, sensitive root causes of a systemic problem
The correct answer accurately reflects the figurative meaning of the idiom "poner el dedo en la llaga" in an academic presentation setting, which means to target and confront the exact, sensitive root of a difficult issue. The surrounding discourse reinforces this through explicit contrast with cosmetic measures ("no buscaba una solución cosmética") and alignment with deep systemic remedies ("abordar de raíz la marginación histórica").

Step-by-Step Solution

1
Analyze the rhetorical context and contrast markers in the presentation excerpt.
The speaker contrasts a superficial intervention ("no buscaba una solución cosmética") with a profound initiative aimed at addressing historical inequality at its core ("abordar de raíz").
Contextual contrasts clarify that the target expression represents tackling fundamental structural issues rather than minor surface symptoms.
2
Interpret the figurative meaning of the Spanish idiom "poner el dedo en la llaga".
The phrase literally describes touching a wound or sore point, but idiomatically signifies identifying, pointing out, or confronting the most acute and sensitive core of a problem.
Recognizing the metaphorical application to structural inequality confirms the speaker's intent to highlight and remedy core systemic challenges.
3
Evaluate the answer choices against the deduced contextual meaning.
The option specifying direct identification and confrontation of the most critical root causes accurately reflects both the idiomatic definition and the analytical tone of the presentation.
Distractors representing literal medical translations, accusatory tone misinterpretations, or contradictory cosmetic remedies are systematically eliminated.

Durante décadas, los pequeños agricultores de la provincia de Chimborazo han dependido exclusivamente de métodos ancestrales para predecir el clima y organizar sus ciclos de siembra. Sin embargo, las alteraciones climáticas recientes han vuelto impredecibles las temporadas de lluvia, provocando pérdidas considerables en las cosechas de papa y quinua.

Para enfrentar esta problemática, un grupo de ingenieros agrónomos de la Universidad Central ha desarrollado una aplicación móvil comunitaria llamada *Allpa*. Esta herramienta recopila datos meteorológicos en tiempo real mediante sensores locales accesibles y envía alertas sencillas directamente a los teléfonos móviles de los campesinos.

El impacto principal de este proyecto no radica únicamente en la adopción de teléfonos inteligentes, sino en cómo la integración de herramientas tecnológicas modernas fortalece la resiliencia comunitaria y asegura la sostenibilidad alimentaria de las familias rurales ante los desafíos del cambio climático. Con más de quinientas familias beneficiadas en su primer año, *Allpa* demuestra que la ciencia aplicada puede convivir en armonía con los saberes locales.

¿Cuál es la idea principal del informe auditivo?

An instructor in an applied biotechnology laboratory provides oral instructions regarding the extraction and concentration of secondary metabolites from plant tissues:

"Before introducing the dried botanical sample into the extraction vessel, you must thoroughly homogenize the dried leaves using a sterile mortar and pestle. However, prior to performing any grinding, ensure that the ethanol-water solvent mixture has already been chilled to 4°C. Once the pulverized material is submerged in the chilled solvent and macerated for thirty minutes, centrifuge the suspension to separate the solid biomass from the liquid. Finally, only after the liquid supernatant has been completely passed through a fine membrane filter should you transfer it to the rotary evaporator flask for concentration."

Based on the transitional markers and conditional timing in the audio instructions, arrange the following actions in the exact chronological order in which they must be performed.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological order is: 1) Verify that the ethanol-water solvent mixture is chilled to 4°C, 2) Homogenize the dried botanical leaves using a sterile mortar and pestle, 3) Centrifuge the suspension to separate the solid biomass from the liquid, and 4) Pass the liquid supernatant completely through a fine membrane filter.
Correctly arranging these instructions requires interpreting temporal transitions rather than relying on the linear order of speech. The marker 'prior to performing any grinding' places chilling the solvent mixture before leaf homogenization. Next, 'before introducing the sample' positions leaf homogenization prior to submerging and macerating. Following maceration, 'once...' signals that centrifugation takes place next. Finally, 'only after...' designates membrane filtration as the final prerequisite step before transferring the solution to the rotary evaporator.

Step-by-Step Solution

1
Identify prerequisite conditions established by reverse transitional markers.
Determined that chilling the solvent mixture must occur before any leaf grinding takes place.
The phrase 'prior to performing any grinding' establishes an inverted temporal relationship relative to the order of speech.
2
Locate the primary sample preparation step governed by forward-looking temporal markers.
Determined that leaf homogenization takes place second.
Homogenization is prescribed 'Before introducing the dried botanical sample into the extraction vessel', immediately following the chilled solvent verification.
3
Identify the intermediate procedural transition.
Determined that centrifugation is the third operational step.
The sequential marker 'Once the pulverized material is submerged... and macerated' indicates that centrifugation follows solvent exposure.
4
Determine the concluding conditional action.
Determined that membrane filtration is the fourth action before final rotary evaporation.
The restrictive conditional marker 'Finally, only after... has been completely passed through a fine membrane filter' mandates filtration prior to concentration.

Question 939Question →

The following transcript is from a podcast examining the intersection of modern agricultural technology and traditional Latin American artisanal practices.

Host: 'The introduction of CRISPR-edited agave strains into Oaxacan mezcal production has unquestionably averted an agricultural catastrophe. Following years of severe drought, these modified plants are yielding piñas with a 60% higher fermentable sugar content, effectively rescuing hundreds of generational palenques from bankruptcy. From a purely agronomic standpoint, it is a miraculous intervention. Nevertheless, as the erratic, stress-induced chemical compounds—the very terpenes that historically endowed each village's mezcal with its unmistakable, smoky terroir—are bred out in favor of standardized resilience, one has to interrogate what we are actually distilling. The master mezcaleros are undoubtedly experiencing a desperately needed financial reprieve. However, this biologically optimized iteration of the spirit, while chemically flawless and abundant, systematically erases the chaotic environmental dialogue that once gave the drink its profound soul.'

Which of the following most accurately analyzes the host’s complex perspective on the technological modernization of mezcal production?

Show answer & explanation

Answer: While the host validates the vital agricultural and financial salvation provided by the new agave, they ultimately adopt a tone of melancholic caution, suggesting that biological optimization is stripping the spirit of its unique environmental essence.

Answer

While the host validates the vital agricultural and financial salvation provided by the new agave, they ultimately adopt a tone of melancholic caution, suggesting that biological optimization is stripping the spirit of its unique environmental essence.
The correct answer accurately captures the dual nature of the host's commentary. First, it acknowledges the 'agricultural and financial salvation' (referenced in the text by the rescue from bankruptcy and increased sugar content). Second, it correctly identifies the shift to 'melancholic caution' and the concern over stripped 'environmental essence' (supported by the host's lament over the erasure of the 'chaotic environmental dialogue' and unique 'terroir').

Step-by-Step Solution

1
Analyze the first half of the transcript to identify the initial tone and subject matter.
The host discusses 'rescuing hundreds of generational palenques from bankruptcy' and a 'miraculous intervention,' acknowledging significant economic and agricultural improvements.
Establishing the baseline perspective is necessary to understand the speaker's overall stance and any subsequent shifts.
2
Examine transitional words and the subsequent change in rhetoric.
The word 'Nevertheless' signals a pivot. The host begins to question 'what we are actually distilling' and refers to the loss of 'erratic, stress-induced chemical compounds.'
Transitional markers often indicate a shift from objective reporting to subjective commentary or a counter-perspective.
3
Interpret the figurative language and vocabulary used in the concluding sentences.
Phrases like 'biologically optimized iteration,' 'systematically erases,' and 'chaotic environmental dialogue' reveal a deep sense of loss and skepticism.
Figurative language carries the emotional weight and true perspective of the speaker, distinguishing subjective opinion from literal facts.
4
Synthesize the findings to determine the overarching tone and perspective.
The host balances undeniable economic success with a profound lament for the loss of unique terroir, resulting in a melancholic and cautionary tone.
A level 5 analysis requires integrating conflicting ideas (economic triumph vs. cultural/environmental loss) to capture the speaker's nuanced complexity.

Agradecemos su colaboración para celebrar nuestras tradiciones con civismo y orden.»

Based on the announcement and its regional cultural context, which of the following best explains the specific operational restrictions imposed on transit passengers?

Show answer & explanation

Answer: The transit system is regulating passenger flow and restricting oversized floral displays on trains to balance commuter safety with the city's signature cultural parade.

Answer

The transit system is regulating passenger flow and restricting oversized floral displays on trains to balance commuter safety with the city's signature cultural parade.
The correct response accurately reflects the announcement's cultural and situational context: the transit network in Medellín is managing heavy passenger volume and diverting large traditional parade structures (*silletas*) to storage bays during the *Feria de las Flores*, ensuring both civic mobility and participation in regional heritage.

Step-by-Step Solution

1
Identify the regional cultural context of the audio announcement.
The announcement refers to the *Feria de las Flores* and *Desfile de Silleteros* in Medellín, Colombia, which involves large traditional floral arrangements (*silletas*).
Recognizing the cultural tradition helps explain why special transit rules are enacted.
2
Analyze the situational management protocols and civic values stated in the message.
The transit network is establishing capacity controls (*control de aforo*) starting at 14:00 and requiring large ornamental frames (*silletas ornamentales*) to be checked at designated intermodal storage areas rather than carried onto passenger train cars.
These measures ensure public transit functionality while maintaining the local ethos of *Cultura Metro* during a major regional holiday.
3
Synthesize the situational need with the cultural purpose to choose the correct interpretation.
The statement aims to facilitate orderly celebration of the festival while maintaining commuter safety and flow.
Distinguishing between temporary festival crowd management and permanent commercial or structural prohibitions is key to identifying the correct answer.
