Matches

Show answer & explanation

Answer

The correct pairings match 'ante-' with 'Before or prior in time and order', 'circum-' with 'Around or on all sides', 'contra-' with 'Against or in direct opposition', and 'intra-' with 'Within or located on the inside'.
Each prefix corresponds directly to its standard Latin morphological root: 'ante-' indicates priority in time or position ('before'), 'circum-' indicates perimeter or surrounding movement ('around'), 'contra-' indicates contrary action or resistance ('against'), and 'intra-' denotes internal containment ('within').

Step-by-Step Solution

1
Analyze the prefix 'ante-' and examine its root function.
'ante-' functions as a temporal and spatial prefix meaning 'before' or 'preceding' (e.g., antecedent, antedate).
Isolating the temporal meaning matches it with prior time and order.
2
Analyze the prefix 'circum-' and examine its root function.
'circum-' specifies a perimeter or spatial enclosure meaning 'around' or 'about' (e.g., circumference, circumscribe).
Recognizing spatial boundary relations verifies the match with surrounding or on all sides.
3
Analyze the prefix 'contra-' and examine its root function.
'contra-' indicates opposition or conflict meaning 'against' or 'contrary' (e.g., contradict, contravene).
Identifying oppositional morphology links the prefix directly to direct opposition.
4
Analyze the prefix 'intra-' and examine its root function.
'intra-' denotes interior confinement meaning 'within' or 'on the inside' (e.g., intravenous, intramural).
Distinguishing interior prefixes from interpersonal or transitional prefixes establishes the internal match.

Items

peri- (as in perimeter, periscope)
dys- (as in dysfunction, dystrophy)
bene- (as in benefactor, beneficial)
trans- (as in transport, transmit)

Matches

Show answer & explanation

Answer

The prefix peri- corresponds to 'Around, surrounding, or enclosing'; dys- corresponds to 'Abnormal, impaired, or bad'; bene- corresponds to 'Good, well, or favorable'; and trans- corresponds to 'Across, through, or beyond'.
Each prefix aligns with its standard morphological definition: 'peri-' means around or surrounding; 'dys-' means abnormal, impaired, or bad; 'bene-' means good, well, or favorable; and 'trans-' means across, through, or beyond.

Step-by-Step Solution

1
Analyze the Greek prefix 'peri-' using recognizable exemplar terms.
In words like 'perimeter' (distance around) and 'periscope' (instrument to view around obstacles), 'peri-' expresses the concept of surrounding or enclosing.
Isolating the morphological boundary identifies the positional/spatial meaning.
2
Analyze the Greek prefix 'dys-' using contextual examples.
In words like 'dysfunction' (impaired operation) and 'dystrophy' (faulty nutrition/development), 'dys-' functions as a negative qualitative marker meaning bad or abnormal.
Differentiating qualitative prefixes prevents confusion with purely locational prefixes.
3
Analyze the Latin prefix 'bene-' and its antonymous relationships.
In words like 'beneficial' and 'benevolent', 'bene-' consistently contributes the meaning of good or well.
Connecting prefixes to known Latin roots confirms positive evaluative meaning.
4
Analyze the Latin prefix 'trans-' across physical and directional uses.
In words like 'transport' (carry across) and 'transmit' (send through/across), 'trans-' denotes movement across or through.
Determining directional prefixes completes the distinct set of pairings.

Fill in the blanks below

Working late into the night without sufficient sleep proved to be , as it actually reduced the team's overall productivity.
Show answer & explanation

Answer

counterproductive
The word 'counterproductive' correctly completes the sentence. The prefix 'counter-' originates from Latin (contra) meaning 'against' or 'opposite.' When affixed to 'productive,' it precisely describes an action that hinders rather than helps progress, matching the contextual clue that the action 'actually reduced' overall productivity.

Step-by-Step Solution

1
Analyze the context of the sentence
The sentence describes an action intended to increase output that instead resulted in the opposite outcome (reduced productivity).
Contextual clues indicate an oppositional or self-defeating result rather than simple inactivity.
2
Apply the appropriate prefix meaning 'against' or 'opposite' to the base word 'productive'
Combining the prefix 'counter-' with 'productive' yields 'counterproductive'.
