Question 3942Question →

A military supply convoy travels from Base Alpha to Base Bravo, a distance of 180 miles, and then returns along the exact same route. Fully loaded on the outbound trip, the convoy vehicles average 12 miles per gallon (MPG). Empty on the return trip, they average 15 MPG. If standard diesel fuel costs $4.00 per gallon, what is the total cost of fuel consumed by one vehicle for the entire round trip?

Show answer & explanation

Answer: $108.00

Answer

The total cost of fuel for the round trip is $108.00.
The correct answer accurately determines the total fuel by breaking the round trip into two separate legs with different efficiencies. The outbound leg requires 15 gallons (180 / 12) and the return leg requires 12 gallons (180 / 15), for a total of 27 gallons. Multiplying this total by the 4.00pricepergallonyields4.00 price per gallon yields 108.00.

Step-by-Step Solution

1
Calculate the fuel consumed on the outbound trip.
180 miles / 12 MPG = 15 gallons
Dividing distance by fuel efficiency gives the amount of fuel used for the first leg.
2
Calculate the fuel consumed on the return trip.
180 miles / 15 MPG = 12 gallons
The return trip covers the same distance but at a different fuel efficiency because the vehicle is empty.
3
Determine the total amount of fuel consumed for the entire round trip.
15 gallons + 12 gallons = 27 gallons
Adding the fuel from both legs gives the total fuel requirement.
4
Calculate the total cost of the fuel.
27 gallons * 4.00/gallon=4.00/gallon = 108.00
Multiplying the total gallons used by the price per gallon yields the final cost.

Isolate the root morpheme within the target word.
The word *transmit* divides into the prefix *trans-* (meaning across) and the root *mit*.
Separating prefixes from the root exposes the foundational morpheme carrying the core definition.
2
Determine the foundational meaning of the Latin root *mit*.
The root *mit* means 'to send', giving *transmit* the literal definition of 'to send across'.
Recognizing cognates like *emit* (send out) and *submit* (send under) verifies this definition.

Key Concept

The Latin root *mit* (and its variant *miss*) means 'to send'.

Question 3944Question →

In marine propulsion, cavitation develops when localized pressure drops in the fluid cause microscopic vapor bubbles to form and violently implode against moving components. While operators frequently identify cavitation by its distinctive acoustic signature and hull vibration, the primary operational hazard of cavitation is the severe physical erosion and surface pitting it inflicts on propeller blades over time. The concentrated energy released during bubble collapse continually strips protective coatings, degrades structural integrity, and alters hydrodynamic efficiency. Consequently, naval engineering protocols mandate strict operational speed limits and routine acoustic monitoring specifically to reduce the rate of this destructive surface wear.

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

Show answer & explanation

Answer: Cavitation poses a major operational hazard primarily because it causes progressive physical erosion and structural damage to propeller blades.

Radar operators on naval vessels must maintain continuous visual monitoring of display screens to ensure navigational safety. During night operations, surface clutter and atmospheric interference can obscure small vessels or floating obstacles. By constantly adjusting gain settings and tracking signal returns, operators identify potential collision hazards before they pose an immediate threat.
Standard pre-flight inspections are mandatory for military aircraft to prevent mechanical failure during flight. Ground crews systematically inspect control surfaces, hydraulic lines, and engine cowlings for loose fasteners or fluid leaks. Identifying and repairing minor component wear before takeoff eliminates operational hazards and guarantees mission readiness.
Wearing layered clothing is the most effective method for personnel to prevent hypothermia in Arctic environments.

Question 3954Question →

A food service manager is organizing supplies based on capacity. Arrange the following containers of cooking oil in order from the smallest volume to the largest volume.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence from smallest to largest is: the 1010 fluid ounce bottle, the 22 cup jar, the 22 quart pitcher, and the 11 gallon jug.
The correct order is determined by converting all container measurements to a single standard unit, such as fluid ounces. The bottle (1010 fluid ounces) is the smallest. Next is the jar (22 cups), which equals 1616 fluid ounces. Then comes the pitcher (22 quarts), which is 6464 fluid ounces. Finally, the bulk jug (11 gallon) is the largest at 128128 fluid ounces.

Step-by-Step Solution

1
Identify a common unit of measurement to compare all the containers.
Fluid ounces is the smallest and most direct base unit to use for comparison.
Converting all volumes to fluid ounces allows for an accurate numerical comparison of capacities.
2
Evaluate the capacity of the small bottle.
The bottle holds 1010 fluid ounces.
It is already provided in the target base unit.
3
Convert the capacity of the jar (22 cups) into fluid ounces.
2×8=162 \times 8 = 16 fluid ounces.
Standard US capacity conversion states that 11 cup is equal to 88 fluid ounces.
4
Convert the capacity of the pitcher (22 quarts) into fluid ounces.
2×32=642 \times 32 = 64 fluid ounces.
Standard US capacity conversion states that 11 quart is equal to 3232 fluid ounces.
5
Convert the capacity of the bulk jug (11 gallon) into fluid ounces.
11 gallon equals 128128 fluid ounces.
Standard US capacity conversion states that 11 gallon contains exactly 128128 fluid ounces.
6
Order the converted numerical values from smallest to largest.
10<16<64<12810 < 16 < 64 < 128.
This mathematically corresponds to the original sequence of containers: bottle, jar, pitcher, jug.

Question 3955Question →

During the tense border negotiations, the commander maintained an increasingly bellicose tone. What does the word bellicose most nearly mean?

Show answer & explanation

Answer: combative

Answer

combative
The word 'bellicose' derives from the Latin root 'belli-' (meaning 'war' or 'fighting') and the suffix '-ose' (meaning 'full of' or 'inclined to'). Therefore, the meaning of 'bellicose' is inclined to fight or aggressive, making 'combative' the exact synonym.

Step-by-Step Solution

1
Isolate the root of the target word
The target word 'bellicose' contains the Latin root 'bell-' / 'belli-' (from 'bellum'), which means 'war' or 'fighting'.
Analyzing root morphology allows deduction of the core meaning of unfamiliar vocabulary.
2
Match the core root meaning to the closest answer choice
'Combative' directly aligns with the concept of being eager or ready to fight.

Question 3956Question →

Despite hours of mediation, the committee members maintained an intransigent posture regarding the bylaws. What does the word intransigent most nearly mean?

Show answer & explanation

Answer: Unwilling to compromise or change views

Answer

Unwilling to compromise or change views
The word is formed by the negative prefix 'in-' (meaning 'not') and the root 'transigent' (meaning 'compromising'). Therefore, the word describes an entity that is inflexible and refuses to yield, which perfectly fits the context of stalled mediation.

Step-by-Step Solution

1
Identify the prefix and the root of the target word.
The word 'intransigent' consists of the prefix 'in-' attached to the base 'transigent'.
Breaking a complex vocabulary word into its morphological components helps reveal its core meaning.
2
Determine the meaning of the prefix.
The prefix 'in-' functions as a negative modifier, meaning 'not' or 'without'.
Recognizing common prefixes is essential for decoding words structurally.
3
Synthesize the components with the sentence context.
Combining 'not' with 'transigent' (compromising) produces 'not compromising', which aligns logically with maintaining a rigid posture during a mediation.
Confirming the structural meaning against the context ensures the correct definition is selected and avoids antonym traps.

Question 3957Question →

The expedition leader was recognized for her tenacity in navigating the treacherous mountain terrain.

Which of the following words correctly uses an adjective suffix to describe an individual characterized by this quality?

Show answer & explanation

Answer: tenacious

Answer

The word 'tenacious' is the correct choice because the suffix '-ous' forms an adjective meaning 'characterized by' or 'full of' the persistent quality of tenacity.
The word 'tenacity' uses the noun suffix '-ity' to name the quality of holding firm. To convert this meaning into an adjective describing a person, the suffix '-ous' (in the form '-acious') is added to create 'tenacious', which means persistently holding fast.

Step-by-Step Solution

1
Analyze the base word 'tenacity' to determine its root and current syntactic function.
The word consists of the Latin root 'ten-' (to hold firmly) combined with the noun suffix '-ity', which denotes an abstract state or quality.
Identifying the root meaning and original part of speech is necessary to find the corresponding adjective derivative.
2
Identify the required part of speech and appropriate derivational suffix.
The prompt requires an adjective describing an individual possessing this trait, which is formed by adding the adjective suffix '-ous' (as '-acious').
The suffix '-ous' functions morphologically to convert base concepts into qualifying adjectives meaning 'having the quality of'.
3
Evaluate the answer choices against part-of-speech constraints and semantic alignment.
'Tenacious' correctly fills the grammatical and semantic requirements, while other options are abstract nouns, false look-alikes, or antonyms.
