Question 3621Question →

Despite the chemical solution being expected to remain stable throughout the heating process, the mixture became extremely volatile as the temperature rose. In this sentence, what does the underlined word volatile most nearly mean?

Calm and steady

Harmful and toxic

Unstable and unpredictable

Loud and high in volume

Show answer & explanation

Answer: Unstable and unpredictable

Answer

Unstable and unpredictable

The sentence sets up an explicit contrast using the word 'Despite'. The mixture was expected to remain 'stable', but instead it became 'volatile'. Therefore, 'volatile' must mean the opposite of stable, which is 'Unstable and unpredictable'.

Step-by-Step Solution

1

Identify the contrast marker and opposing clue in the sentence.

The preposition 'Despite' signals a contrast between the expectation of the solution remaining 'stable' and its actual state of becoming 'volatile'.

Recognizing the contrast transition indicates that the target word has an opposite meaning to the clue provided.

2

Determine the meaning opposite to 'stable'.

The opposite of 'stable' is 'unstable and unpredictable'.

Selecting the opposite of the known clue yields the correct definition of the target word.

Key Concept

Question 3623Question →

The investigator delivered a dispassionate summary of the forensic evidence to the board. In this sentence, what does the word dispassionate most nearly mean?

Hostile

Impartial

Enthusiastic

Distracted

Show answer & explanation

Answer: Impartial

Answer

Impartial

The word 'dispassionate' combines the Latin prefix 'dis-' (meaning 'away from' or 'free from') with the base 'passion' and adjective suffix '-ate'. Together, these morphological elements define something that is not influenced by strong emotion or prejudice, which makes 'impartial' the exact synonym.

Step-by-Step Solution

1

Break down the target word into its constituent morphological parts.

The word consists of the prefix dis- (meaning 'apart', 'not', or 'free from'), the base word passion (strong emotion or bias), and the suffix -ate (forming an adjective).

Morphological segmentation reveals how the affixes modify the base meaning.

2

Synthesize the affix meanings to deduce the literal definition.

Dispassionate describes an attitude or evaluation characterized by being free from personal passion, bias, or emotional involvement.

Combining 'free from' with 'passion' denotes emotional detachment and objectivity.

3

Match the synthesized definition to the closest synonym among the choices.

The term impartial directly corresponds to being objective and free from prejudice or emotional bias.

Both terms describe neutrality and fair judgment without personal favoritism.

Question 3624Question →

Which of the following most nearly means the same as the word 'perfidious'?

Perfunctory

Confident

Treacherous

Steadfast

Show answer & explanation

Answer: Treacherous

Answer

Treacherous

The correct answer accurately reflects the morphological breakdown of 'perfidious'. The prefix 'per-' indicates destruction or moving away from, the root 'fid' means faith or trust, and the suffix '-ious' means full of. Together, they describe someone who is characterized by breaking trust, which is the exact definition of treacherous.

Step-by-Step Solution

1

Identify the root of the target word.

The root is 'fid', derived from the Latin 'fides', meaning faith or trust.

Breaking the word down into its root provides the core semantic meaning.

2

Analyze the prefix and its effect on the root.

The prefix 'per-' in this specific context carries a destructive meaning (away or to destruction), altering the root to mean breaking faith.

Prefixes modify the root's definition; here, it completely reverses the positive connotation of trust.

3

Analyze the suffix to determine the part of speech.

The suffix '-ious' forms an adjective meaning 'characterized by' or 'full of'.

Identifying the suffix ensures the selected synonym matches the target word's grammatical function.

4

Synthesize the morphological parts and select the matching synonym.

The word literally translates to 'characterized by breaking faith.' The option 'treacherous' perfectly matches this definition.

Combining the prefix, root, and suffix meanings reveals the exact definition needed to evaluate the choices.

Fill in the blanks below

Because the field mechanic frequently traveled to remote work sites, he relied on a generator that could be carried with ease.

Show answer & explanation

Answer

portable

The word 'portable' is derived from the Latin root 'port' (meaning 'to carry') and the suffix '-able' (meaning 'capable of being'). In this context, a 'portable' generator is one designed to be moved and carried easily.

Step-by-Step Solution

1

Analyze the sentence context to determine the required meaning

The context describes a machine that must be easy to carry and move between different job locations.

Understanding the context clarifies that the missing word must describe the quality of being transportable by hand.

2

Apply root word knowledge to identify the correct term

The Latin root 'port' means 'to carry,' and combining it with the suffix '-able' (capable of) forms the adjective 'portable.'

Root word analysis confirms that 'portable' literally means capable of being carried.

Question 3626Question →

Aviation fuel storage systems are highly vulnerable to biological degradation when microscopic fungi thrive in stagnant water pockets at tank bottoms. These microorganisms consume hydrocarbons, multiplying rapidly and generating corrosive acidic byproducts. Over time, thick fungal mats can clog fuel filters, corrode internal aluminum lines, and cause erratic fuel gauge readings. Consequently, routinely draining accumulated water from tank sumps is the most effective operational method for preventing microbial contamination in aviation fuel systems.

According to the passage, which of the following expresses the main idea?

Microscopic fungi produce corrosive acidic byproducts while consuming hydrocarbons in fuel tanks.

Thick fungal mats clog engine filters and cause erratic fuel gauge readings in aircraft.

Routinely draining water from tank sumps is the most effective method to prevent microbial fuel contamination.

Aviation fuel storage tanks must be replaced whenever water enters internal fuel lines.

Show answer & explanation

Answer: Routinely draining water from tank sumps is the most effective method to prevent microbial fuel contamination.

Answer

Routinely draining water from tank sumps is the most effective method to prevent microbial fuel contamination.

The passage builds up by explaining how microbial growth occurs in stagnant water and the damage it causes, culminating in the explicit topic sentence in the final line: 'Consequently, routinely draining accumulated water from tank sumps is the most effective operational method for preventing microbial contamination in aviation fuel systems.' The correct option directly reflects this explicit claim.

Step-by-Step Solution

1

Read the passage to identify the central topic and scope.

The text discusses how water causes fungal growth in aviation fuel tanks and concludes with the primary preventive measure.

Understanding the full context helps separate background facts from the core takeaway.

2

Locate the explicit topic sentence that unifies the paragraph.

The concluding sentence explicitly states: 'Consequently, routinely draining accumulated water from tank sumps is the most effective operational method for preventing microbial contamination in aviation fuel systems.'

Expository technical paragraphs often place the explicit main idea in the final sentence as a synthesis or conclusion.

3

Match the explicit statement to the corresponding answer choice.

The option stating that routinely draining water from tank sumps is the most effective method directly paraphrases the explicit topic sentence.

The correct response must capture the main idea rather than isolated supporting details or unstated exaggerations.

Question 3629Question →

A circular water pipe has a diameter of $8$ inches. What is the cross-sectional area of the pipe? Use $\pi = 3.14$ .

Show answer & explanation

Answer: 50.24

Answer

50.24 square inches

The area of a circle is calculated using the formula

A = \pi r^2

. First, find the radius by dividing the diameter by 2 (

8 \div 2 = 4

). Then, substitute

r = 4

and

\pi = 3.14

into the formula:

A = 3.14 \times 4^2 = 3.14 \times 16 = 50.24

.

Step-by-Step Solution

1

Find the radius of the pipe.

Radius = 4 inches

The formula for the area of a circle requires the radius, which is exactly half of the diameter.

2

Calculate the cross-sectional area using the area formula.

Area = 50.24 square inches

Squaring the radius (16) and multiplying by 3.14 gives the total area of the circle.

Read the sentence below and use the contrast clue to determine the missing term. Which word best completes the blank?

Fill in the blanks below

Although the initial radio transmission was muffled and completely inaudible, the backup broadcast came through crystal .

Show answer & explanation

Answer

clear (or audible / distinct)

The sentence begins with the transition word 'Although', establishing a direct contrast between the two clauses. The first transmission is described as 'inaudible' (meaning impossible to hear), so the backup broadcast must be described by its opposite. The word 'clear' accurately completes the contrast and fits the standard phrase 'crystal clear'.

Step-by-Step Solution

1

Locate the contrast signal word and the context clue.

The conjunction 'Although' signals an opposing relationship to the descriptive clue 'inaudible'.

Contrast transition words indicate that the two connected clauses describe opposite conditions.

2

Identify the antonym of the clue word that fits the sentence context.

The antonym of 'inaudible' (unable to be heard) in the context of a radio transmission is 'clear' or 'audible'.

Supplying an antonym completes the contrast established between the failed initial transmission and the successful backup broadcast.

Question 3638Question →

A contractor is applying a specialized primer to a rectangular warehouse wall that is $60\text{ feet}$ long and $18\text{ feet}$ high. The wall contains a rectangular loading bay door measuring $30\text{ feet}$ long and $12\text{ feet}$ high, which will not receive the primer. If the primer material costs $\$15$ per square yard, what is the total cost, in dollars, of the primer needed for the wall?

Show answer & explanation

Answer: 1200

Answer

1200

The total gross area of the wall is

60 \times 18 = 1080\text{ square feet}

. The area of the unpainted loading door is

30 \times 12 = 360\text{ square feet}

. Subtracting the door's area yields a net area of

720\text{ square feet}

to be primed. Because

1\text{ square yard}

equals

9\text{ square feet}

, the net area in square yards is

720 \div 9 = 80\text{ square yards}

. Finally, multiplying the

80\text{ square yards}

by the

\$15

cost per square yard gives a total cost of

\$1200

.

Step-by-Step Solution

1

Calculate the gross area of the warehouse wall.

1080\text{ sq ft}

Multiply the length (

60\text{ feet}

) by the height (

18\text{ feet}

) to find the total rectangular area before accounting for the door.

2

Calculate the area of the loading bay door.

360\text{ sq ft}

Multiply the door's length (

30\text{ feet}

) by its height (

12\text{ feet}

) to determine the area that will not be painted.

3

Find the net area to be primed.

720\text{ sq ft}

Subtract the area of the door from the gross wall area (

1080 - 360

) to find the exact surface area requiring primer.

4

Convert the net square footage into square yards.

80\text{ sq yd}

Since the cost is given per square yard, and there are

9\text{ square feet}

in

1\text{ square yard}

(

3\text{ ft} \times 3\text{ ft}

), divide the net area by 9 (

720 \div 9

).

5

Calculate the total cost of the primer.

\$1200

Multiply the required area in square yards (

80

) by the cost per square yard (

\$15

).
