While the research team anticipated that the newly discovered primate species would exhibit aggressive territorial behavior, the field data gathered over three seasons revealed a distinctly ________ demeanor, surprising observers with frequent acts of food-sharing and social cooperation. Which of the following words best completes the sentence in accordance with the contextual tone clues?
- congenialAnswer
- Bbellicose
- Cangelic
- Dsolitary
- Epugnacious
Answer
The word 'congenial' correctly fits the blank by establishing a positive, friendly demeanor that contrasts with the expected aggression.
The sentence relies on the contrast signal 'While' to set up an opposition between expected 'aggressive territorial behavior' and actual observed behavior. The descriptive clue 'frequent acts of food-sharing and social cooperation' requires a word denoting a friendly, harmonious, and cooperative disposition. The word 'congenial' perfectly captures this pleasant and agreeable demeanor within a measured, scientific context.
