Items

The harbor pilot verified the loaded cargo vessel's maximum draft before navigating through the shallow shipping channel.
The technical writer submitted a rough draft of the maintenance manual to the team lead for initial feedback.
Technicians felt a noticeable cold draft coming through the unsealed seam of the hangar bay door.
During the conflict, the government reinstated the military draft to ensure sufficient personnel for defense operations.

Matches

Show answer & explanation

Answer

Each sentence matches its respective specialized definition of 'draft': the cargo vessel sentence aligns with the vertical water depth measurement of a ship, the maintenance manual sentence corresponds to a preliminary written version, the hangar bay sentence represents an air current, and the defense operations sentence signifies compulsory military conscription.
The correct matches pair each specific usage of 'draft' with its exact contextual definition: the maritime sentence uses 'draft' to mean vessel water depth, the workplace sentence uses it for an unfinalized document, the facility sentence refers to a current of cool air, and the government policy sentence refers to mandatory military conscription.

Step-by-Step Solution

1
Analyze the context clues in each sentence to identify the operational domain.
Identified naval navigation ('cargo vessel', 'shallow shipping channel'), administrative documentation ('maintenance manual', 'initial feedback'), environmental conditions ('cold', 'hangar bay door'), and military mobilization ('defense operations', 'personnel').
Contextual domain clues isolate the intended nuance of a polysemous word.
2
Match each contextual usage to its corresponding formal definition.

Question 190Question →

Read the two statements below. What single word correctly fills both blanks to satisfy the specific contextual meaning of each sentence?

Fill in the blanks below

Statement 1: The naval patrol boat navigated into the protected to refuel before the severe weather arrived.

Statement 2: A professional aircraft technician must never doubts about flight safety without reporting them immediately.
Show answer & explanation

Answer

harbor (or harbour)
The polysemous word 'harbor' functions in Statement 1 as a noun referring to a sheltered area of water where ships anchor or dock safely. In Statement 2, 'harbor' functions as a verb meaning to hold, entertain, or keep an internal feeling or thought in mind, such as doubts or reservations. Therefore, 'harbor' correctly completes both sentences.

Step-by-Step Solution

1
Analyze the context of Statement 1 to determine the missing word's part of speech and meaning.
In Statement 1, the context of a 'naval patrol boat' entering a 'protected' area to 'refuel' indicates a noun denoting a sheltered body of water or port for watercraft.
The maritime setting and vessel navigation require a noun referring to a safe anchorage.
2
Analyze the context of Statement 2 to determine the missing word's part of speech and meaning.
In Statement 2, the phrase 'must never [blank] doubts' requires a transitive verb meaning to hold, entertain, or maintain a feeling or belief internally.
The maintenance and safety context requires a verb that pairs idiomatically with internal concerns or doubts.
3
Identify the shared polysemous word that satisfies both contextual roles.
The word 'harbor' functions both as a noun meaning a sheltered port and as a verb meaning to hold or keep a thought or feeling in mind.
Selecting the single lemma that resolves both distinct definitions satisfies the dual contextual requirements.

Question 192Question →

After completing a rigorous inspection of the aircraft's fuselage, the maintenance officer confirmed that the frame was completely sound and cleared for flight. In this sentence, the word sound most nearly means which of the following?

Show answer & explanation

Answer: sturdy

Answer

The word sound most nearly means sturdy.
The sentence specifies that after a thorough inspection, the frame was approved and cleared for flight. In structural and mechanical contexts, the adjective 'sound' denotes an object that is robust, intact, structurally stable, and free from defect, which aligns precisely with 'sturdy.'

Analyze the sentence context and surrounding clues
The target word describes an aircraft frame following a 'rigorous inspection' that resulted in being 'cleared for flight.'
Contextual clues indicate the condition of the frame is safe, undamaged, and structurally capable.
2
Evaluate the secondary and primary meanings of the polysemous word
While the target word commonly refers to noise or hearing (acoustic), its secondary adjective definition means solid, robust, or free from flaw or decay.
Polysemous words require selecting the definition that fits the specific syntax and domain of the sentence.
3
Match the contextual definition with the appropriate option
The meaning 'solid and undamaged' corresponds directly to 'sturdy.'
Substituting 'sturdy' into the sentence preserves the original meaning and logical flow.

Fill in the blanks below

Sentence 1: The seasoned captain was confident that the naval vessel could the severe coastal gale.
Sentence 2: A sudden shift in regional atmospheric conditions brought cold and rainy across the training base.
Show answer & explanation

Answer

The single polysemous word that correctly completes both blanks is 'weather'.
The word 'weather' is a polysemous word with distinct meanings across parts of speech. In the first sentence, it functions as a verb meaning to endure, survive, or come through a storm safely. In the second sentence, it functions as a noun referring to atmospheric conditions such as rain, temperature, and wind. Therefore, 'weather' satisfies both context requirements accurately.

Step-by-Step Solution

1
Analyze the context and grammatical function required for the first sentence.
The first sentence requires a transitive verb following the modal auxiliary 'could' that means to endure, survive, or safely pass through a severe storm or crisis.
The surrounding clues ('seasoned captain', 'naval vessel', 'severe coastal gale') describe withstanding difficult maritime conditions.
2
Analyze the context and grammatical function required for the second sentence.
The second sentence requires a noun functioning as the direct object of 'brought' that refers to meteorological state or atmospheric conditions.
The surrounding clues ('atmospheric conditions', 'cold and rainy') describe physical climate elements.
3
Identify the shared polysemous lemma that satisfies both semantic contexts.
The word 'weather' operates both as a verb meaning 'to withstand or survive' and as a noun meaning 'atmospheric meteorological conditions'.
'Weather' is the only standard English word matching both specific grammatical and contextual requirements.

1
Identify the target word and examine the sentence for surrounding context clues.
The appositive phrase 'an unstable and hazardous state' immediately follows and clarifies the word 'precarious'.
Appositives set off by commas frequently provide direct definitions or paired synonyms for unfamiliar terms.
2
Evaluate the answer choices to identify the term that best matches the meaning provided in the clue.
The word 'unstable' directly matches the definition of something at risk of falling or failing.

The target word functions as an action verb meaning to climb or surmount an obstacle.
Terms such as 'tactical field training', 'obstacle wall', and 'within two minutes' describe physical ascent.
3
Evaluate the context clues in the third sentence concerning laboratory measurements and fuel mixture preparation.
The target word represents a physical instrument used to measure weight.
Phrases like 'weighed each chemical component' and 'electronic' identify a measuring device.
4
Assess the context clues in the fourth sentence addressing supply chain shortages and monthly output quotas.
The target word means to adjust or diminish the scope or volume of production.
The phrasal verb construction 'scale back' paired with 'monthly output quota' signifies proportional reduction.
