Context Clues - Contrast/antonym

Read the sentence: After the long hike, I felt lethargic, but my brother was still energetic enough to play soccer. What does the word lethargic most likely mean?

• Excited and happy

• Tired and slow-moving

• Hungry and thirsty

• Annoyed and frustrated

Answer explanation

The word 'but' signals a contrast between how the speaker felt and how their energetic brother felt. Since the brother was energetic, 'lethargic' must mean the opposite, which is tired and slow-moving.

Match each vocabulary word to the sentence that uses its antonym in a contrasting context.

• The issue was not a significant problem; on the contrary, it was a minor inconvenience.

• serene

• The hero was bold and daring, in stark contrast to the timid kitten hiding under the bed.

• trivial

• The park was a peaceful oasis, unlike the chaotic city streets just a block away.

• courageous

• While my brother was pessimistic about our chances, I still felt we could win.

• optimistic

Answer explanation

The task is to find the antonym (opposite) of each vocabulary word within a sentence that shows a contrast. 'Serene' is the opposite of 'chaotic,' 'trivial' is the opposite of 'significant,' 'optimistic' is the opposite of 'pessimistic,' and 'courageous' is the opposite of 'timid.' The contrast words in the sentences (e.g., 'unlike,' 'on the contrary,' 'while,' 'in contrast to') are clues.

The contrast word 'however' shows that 'concise' is the opposite of the council member's 'long, rambling talk.' Therefore, 'concise' means brief and to the point.
