What is the interpretation of the underlined idiomatic expression as used in the sentence?

After several hours of intense negotiation, the union leaders finally agreed to ______ to the state government's terms. Which of the following phrasal verbs correctly completes the sentence?

Read the passage below carefully:

Despite expanding arid conditions across Nigeria's Sahelian belt, the systematic cultivation of Acacia senegal—the primary source of commercial gum arabic—offers a vital ecological and economic strategy for long-term land restoration. By stabilizing fragile topsoil with deep root structures and fixing nitrogen to replenish depleted nutrients, these drought-resistant trees actively reverse desert encroachment while converting degraded scrubland into arable soil. Concurrently, international demand for gum arabic in pharmaceuticals and confectionery creates a lucrative export stream for rural farming cooperatives, effectively diversifying local incomes away from rain-fed subsistence crops. Although local youth organizations occasionally organize annual cultural festivals around the harvest season and regional artisanal co-ops have introduced decorated wooden tapping knives to commemorate traditions, such socio-cultural activities remain entirely peripheral to the species' core ecological and economic functions. Ultimately, embedding Acacia senegal within community-led agroforestry frameworks represents the single most indispensable pillar for securing both environmental sustainability and rural financial resilience in Northern Nigeria.

Based on the passage, match each statement (1–4) to its corresponding summary classification.

Which word correctly completes the idiomatic expression in the sentence below?

Read the passage below carefully:

The rapid encroachment of agricultural monoculture and urban expansion across the Nsukka plateau in Enugu State has severely threatened numerous indigenous medicinal plants long relied upon by local healers. To prevent the permanent loss of these species, a community-led conservation initiative established decentralized seed banks that store preserved germplasm alongside documented ethnobotanical knowledge. By integrating traditional seed-saving methods with low-cost, solar-powered refrigeration, the project maintains seed viability despite frequent power outages. Consequently, local healers and agricultural researchers can now systematically cultivate rare flora, safeguarding both ecological biodiversity and traditional healthcare practices against environmental degradation.

Which of the following statements best summarizes the passage?

Read the passage excerpt below:

"When the lead architect presented the revised master plan for the metropolitan transportation network, the municipal board enthusiastically hailed it as a monumental leap forward, oblivious to the reality that the entire scheme was built on a foundation of sand."

In the context of the passage above, what does the figurative expression "built on a foundation of sand" imply about the master plan?

During the economic summit, the finance minister emphasized that while aggressive fiscal expansion could stimulate short-term growth, policymakers must temper their enthusiasm with rigorous debt sustainability analysis to prevent hyperinflation.

In the passage context above, which of the following best captures the meaning of the word temper?

Complete the sentence below by providing the appropriate idiomatic expression.

Read the passage below carefully:

In recent years, the exploitation of geothermal energy along the East African Rift System has emerged as a cornerstone for regional economic resilience. Unlike seasonal hydroelectric dams susceptible to recurring droughts, geothermal plants draw upon constant subsurface thermal reservoirs, providing an uninterrupted baseload power supply. This structural reliability is particularly crucial for decentralized agro-processing hubs, which previously suffered heavy financial losses due to unexpected grid blackouts during peak harvest seasons. For instance, tea processing factories in Kenya’s Rift Valley reported a forty percent reduction in post-harvest spoilage after transitioning to direct geothermal steam applications for leaf drying. Furthermore, localized geothermal power plants eliminate the need for extensive high-voltage transmission lines across difficult terrain, thereby reducing infrastructural overhead. Although the initial capital outlay for deep-well exploration drilling remains formidable—frequently requiring state subsidies or international development loans—the long-term operational cost of geothermal power generation is significantly lower than that of fossil-fuel generators. Consequently, expanding geothermal infrastructure offers a viable pathway toward decoupling industrial growth from carbon emissions while guaranteeing energy security for agrarian communities.

Which of the following statements best synthesizes the core message of the passage while excluding supporting illustrations?

Read the passage below carefully:
'Traffic congestion in the Lagos metropolis has long led to severe economic losses and high carbon emissions. To tackle this, urban planners introduced an AI-driven adaptive traffic signal network across major corridors. The system first collects real-time vehicle density data via roadside cameras and sensor arrays. Next, central algorithms dynamically adjust traffic light durations to clear bottlenecked intersections. Following this automated signal optimization, transit authorities noticed a marked decrease in average travel times and fuel consumption. Ultimately, the successful integration of smart traffic management provided a scalable model for urban mobility in developing mega-cities.'

"During the archival preservation of rare sixteenth-century manuscripts, conservators observed that exposure to fluctuating humidity threatened to weather the delicate parchment. To prevent irreversible damage, experts moved quickly to check the spread of fungal spores. While prominent historians champion immediate public display of the recovered folios, the committee decided to table all exhibition plans until stabilization was complete."
