Pair each isolated vocabulary word on the left with its most precise synonym on the right.

Instead of accepting responsibility for the inventory discrepancy during the quarterly audit, the warehouse manager tried to pass the buck by blaming the newly hired supply clerks. Which of the following is the closest meaning of the bolded phrase?

Which word correctly completes the sentence below to form an idiomatic expression that means to deduce an implicit or unstated meaning?

Complete the statement to identify the exact synonym for the bolded word. What word best fills the blank?

Determine the underlying base word for the term in the statement below. What is the base word after removing all affixes?

The mediator agreed to intercede in the dispute before negotiations broke down completely. What does the word intercede most nearly mean in this sentence?

Examine the three technical maintenance briefings below. Which explicitly stated central idea belongs to each briefing?

Complete the equivalence statement by providing an exact, single-word synonym for the capitalized term. Which term correctly fills the blank?

Galvanic corrosion presents a relentless threat to metal ships operating in saltwater environments, where dissimilar metals submerged in an electrolyte generate an electrical current that accelerates metal degradation. To counteract this deterioration, shipbuilders attach sacrificial anodes—typically blocks of highly reactive zinc or aluminum—directly to the vessel's steel hull. Because these anodes possess a lower electrochemical potential, they corrode preferentially, releasing electrons that safeguard the underlying steel structure. However, once these sacrificial blocks deplete completely, the galvanic reaction immediately targets the hull itself, making scheduled inspections and timely replacement indispensable for preserving structural integrity.

Which of the following statements best summarizes the passage?

During World War I, British merchant vessels were painted with complex patterns of geometric shapes, contrasting stripes, and optical illusions rather than solid ocean greys. These chaotic designs did not conceal the ships on the open water. Instead, the intersecting angles broke up each vessel's visual profile, making it difficult for submarine commanders to accurately estimate its heading, speed, and distance through a periscope. As a result, enemy torpedo gunners frequently miscalculated their firing angles and missed their targets.

Which of the following best expresses the unstated main idea of the passage?

Read the three technical excerpts below regarding specialized military hardware. Match each passage with its explicitly stated main idea.

Read each short passage below carefully. Match each passage with the unstated central claim (implicit main idea) it best supports.

Read the following passage about automotive maintenance:

In modern automotive braking systems, regular maintenance is essential to prevent mechanical failure. When brake fluid absorbs excessive moisture over time, its boiling point drops significantly, which causes brake fade during heavy braking. Additionally, worn brake pads create direct metal-to-metal contact with the rotors, resulting in severe surface grooving and loud grinding noises. If air bubbles enter the hydraulic lines due to a loose bleeder valve, the pedal feels spongy because air compresses under pressure while fluid does not. Addressing these specific issues promptly ensures optimal stopping power.

Based on the passage, match each mechanical cause with its direct stated effect.

A rectangular training pool at a military base is $40$ feet long and $25$ feet wide. It is initially filled with water to a uniform depth of $8$ feet. If $1,500$ cubic feet of water is pumped out of the pool, what is the new depth of the water, in feet?

Read the passage below. Based on the directional and sensor evidence provided, what is the logical conclusion regarding the location of the vent? Fill in the blank to complete the deduction.

Technicians in the motor pool parked several diesel transport trucks outside overnight in sub-zero temperatures. The following morning, the drivers turned the ignition keys, but the engines cranked sluggishly and failed to start. After the maintenance crew wheeled portable heaters into the staging bay and directed warm air onto the fuel tanks and engine blocks for thirty minutes, each vehicle started on the first attempt.

What most likely caused the trucks' initial failure to start?

In deep-water naval operations, sonar detection capabilities are profoundly influenced by the ocean's thermal structure. While surface temperature fluctuations typically degrade acoustic signal integrity by scattering high-frequency waves, the presence of a thermocline—a distinct layer where temperature drops rapidly with depth—creates an entirely different phenomenon. Instead of merely scattering, acoustic energy emitted below this boundary is refracted downward due to the increased water density. Consequently, this downward refraction prevents the sound waves from reaching surface receivers, creating an acoustic shadow zone. Paradoxically, while commanders often attribute sudden communication blackouts in these regions to surface scattering, it is actually the abrupt density gradient within the thermocline that effectively cloaks submerged vessels from shallow-draft tracking vessels.

Based on the passage, what effectively causes a submerged vessel to become cloaked from shallow-draft tracking vessels?

A machinist shaping a precision titanium valve noticed irregular grooves forming along the milled edges of the part. Earlier that morning, the workshop's central coolant pump had experienced a pressure drop, reducing the stream of fluid delivered to the cutting head. Upon inspecting the carbide tool immediately afterward, the machinist observed severe blunting on its contact edge.

What most likely led to the irregular grooves on the titanium valve?

Passage:
Prior to performing maintenance on industrial hydrocarbon lines, operators purge the piping with pressurized nitrogen gas rather than atmospheric air. Because hydrocarbons combust only within a specific fuel-to-oxygen ratio, displacing oxygen with chemically inert nitrogen prevents flammable mixtures from forming, even if residual volatile vapors remain inside the conduit. Once the purge is complete, sensors verify that oxygen levels remain below dangerous thresholds before cutting or welding begins.

Statement: Hot maintenance such as welding can proceed safely on purged lines even if volatile hydrocarbon vapors are still present inside the piping.
