Question 21Question →

The inspector noticed that the contractor had miscalculated the total weight of the cargo. In this sentence, what does the word miscalculated mean?

Show answer & explanation

Answer: Calculated incorrectly

Answer

Calculated incorrectly
The correct definition is 'Calculated incorrectly' because the common prefix 'mis-' attaches to verbs and nouns to signify wrongness or error. Combining 'mis-' with 'calculated' yields the meaning of making an arithmetic or judgment error.

Step-by-Step Solution

1
Isolate the prefix and the base word in 'miscalculated'
The prefix is 'mis-' and the base word is 'calculated'
Breaking the word into its morphological components helps reveal its structural meaning.
2
Apply the meaning of the common prefix 'mis-' to the base word
'mis-' means wrongly, badly, or mistakenly; therefore, 'miscalculated' means calculated wrongly or incorrectly
Prefixes modify the root word's core definition in predictable ways.

Key Concept

The prefix 'mis-' conveys the meaning of wrongly, badly, or mistakenly when attached to a base word.

The historical novel described the hermit as a bitter misanthrope who lived far from the neighboring towns. What does the word misanthrope most nearly mean?

Show answer & explanation

Answer: A person who dislikes and avoids human society

Answer

A person who dislikes and avoids human society

Question 24Question →

Despite working together on the committee for several years, the two delegates harbored a deep and persistent antipathy toward each other.

In the sentence above, what does the word antipathy most nearly mean?

Show answer & explanation

Answer: a strong feeling of intense dislike or hostility

Answer

a strong feeling of intense dislike or hostility
The word 'antipathy' derives from the Greek prefix 'anti-' (against) and root 'pathos' (feeling), denoting a settled aversion, hostility, or intense dislike.

Step-by-Step Solution

Question 25Question →

Evaluate the morphological components of the medical and scientific terms *somatotype*, *psychosomatic*, and *chromosome*. Which Greek root, denoting 'body' or 'physical matter,' correctly completes the etymological statement below?

Fill in the blanks below

The compound terms *somatotype*, *psychosomatic*, and *chromosome* are all built upon the Greek root , which specifically signifies 'body.'
Show answer & explanation

Answer

somat (or soma / somato)
The Greek root *somat* (or *soma* / *somato-*) directly translates to 'body.' It forms the anatomical base of *somatotype* (body physique category), *psychosomatic* (involving the interaction of mind and physical body), and *chromosome* (literally a 'colored body,' from Greek *chroma* meaning color and *soma* meaning body).

Step-by-Step Solution

1
Isolate the common morpheme shared across the sample words *somatotype*, *psychosomatic*, and *chromosome*.
The common morphological element appearing in all three terms is the root *soma* or *somat-*.
Deconstructing compound words into their constituent morphemes identifies the central base root.
2
Verify the etymological origin and core definition of the identified root.
The Greek noun *soma* (stem *somat-*) literally translates to 'body' or 'physical substance.'
Etymological verification confirms that the root matches the meaning specified in the prompt.
3
Validate the semantic contribution of the root within each context word.
*Somatotype* refers to a classification of human body build; *psychosomatic* refers to physical body symptoms caused by mental processes (*psyche*); *chromosome* refers to a microscopic cellular 'colored body' (*chroma* + *soma*).
Contextual validation ensures the definition is consistent across all examples.

Question 27Question →

Under the microscope, the newly discovered mineral specimen appeared completely amorphous. What does the word amorphous most nearly mean?

Show answer & explanation

Answer: Lacking a clear or definite shape

Answer

Lacking a clear or definite shape

Question 36Question →

The astrophysicist gained widespread attention after proposing a heterodox model of galaxy formation. What does the word heterodox most nearly mean?

Show answer & explanation

Answer: Holding unconventional or differing opinions

Answer

Holding unconventional or differing opinions
The word 'heterodox' derives from the Greek roots 'heteros' (meaning 'other' or 'different') and 'doxa' (meaning 'opinion' or 'belief'). Therefore, a heterodox idea or model is one that deviates from accepted or established doctrines, signifying unconventional or differing beliefs.

Which common Latin prefix meaning 'backward' or 'affecting what is past' correctly completes the sentence below to describe a policy applied to prior events?

Fill in the blanks below

Because the revised compensation agreement applied to work completed during the previous quarter, the accounting department processed the adjustments as active payments.
Show answer & explanation

Answer

retro-
The prefix 'retro-' is derived from Latin and means 'backward', 'behind', or 'back in time'. When attached to the base word 'active', it forms 'retroactive', which specifically describes a statute, rule, or payment that takes effect from a point in the past.

Question 40Question →

Complete the technical passage by converting the base verb 'maintain' into an abstract noun and the root 'perceive' into a qualifying adjective. What words correctly complete the statement?

Fill in the blanks below

Consistent mechanical is vital to ensure that even barely defects in the aircraft frame are discovered prior to flight operations.
Show answer & explanation

Answer

The statement is completed by the noun 'maintenance' for the first blank and the adjective 'perceptible' (or 'perceivable') for the second blank.
The first blank requires a noun denoting the act or process of keeping equipment in working order, formed by combining the base 'maintain' with the noun suffix '-ance' (yielding 'maintenance'). The second blank requires an adjective denoting the ability to be detected or discerned, formed by attaching the adjective suffix '-ible' to the root 'perceive' (yielding 'perceptible').

Step-by-Step Solution

1
Analyze the syntactic role required for the first blank.
The position directly following the adjective 'mechanical' and serving as the subject of the clause requires a noun.
A noun phrase is needed to function as the subject preceding the linking verb 'is'.
2
Apply the appropriate noun suffix and stem vowel shift to 'maintain'.
Adding the noun-forming suffix '-ance' with the morphological shift produces 'maintenance'.
The suffix '-ance' forms action or state nouns from verbs, shifting the spelling from 'maintain' to 'mainten-'.
3
Analyze the syntactic role required for the second blank.
The position modifying the plural noun 'defects' following the adverb 'barely' requires an adjective.
Adverbs modify adjectives which in turn modify nouns within the noun phrase.
4
Apply the appropriate adjective suffix to the root 'perceive'.
Adding the adjective-forming suffix '-ible' (or '-able') produces 'perceptible'.
The suffix '-ible' denotes capability or susceptibility ('capable of being perceived'), forming an evaluative adjective.
