Question

1. look at the word deliberate in the passage below.

the howls, chirps, and squawks of animals might sound random or insignificant to the human ear, but these forms of communication often have particular and vital functions in the animals’ lives. for example, lar gibbons, a species of small apes, intentionally use their calls to form social bonds. researchers discovered that the rhythms of the gibbons’ calls overlap too frequently for the phenomenon to be accidental—in other words, the gibbons combine their hoots in a deliberate way, like performers singing a duet. another group of scientists used recordings to study the sounds made by egyptian fruit bats. they found that the fruit bats make distinct sounds in different situations, such as during a dispute over food or space. these are just two of the countless species whose noises are not as simple as they sound.

what is the meaning of deliberate as used in the passage?

ignorant or unskilled proper or honorable

hasty or reckless purposeful or conscious

Explanation:

To determine the meaning of "deliberate" in the passage, we analyze the context. The passage states that the gibbons' call rhythms overlap too frequently to be accidental, and they combine hoots "like performers singing a duet." The word "intentionally" is also used earlier to describe the gibbons' calls. So "deliberate" here should mean done with purpose or consciously. Let's check the options:

• "ignorant or unskilled": Doesn't match the context of intentional actions.
• "proper or honorable": The passage is about the intentional nature of calls, not about propriety or honor.
• "hasty or reckless": The gibbons' calls are described as intentional, not hasty or reckless.
• "purposeful or conscious": Matches the idea that the gibbons' actions are intentional (not accidental) and done with a purpose, as shown by the comparison to a duet and the use of "intentionally" earlier.

Answer:

D. purposeful or conscious (assuming the last option is D; if the options are labeled differently, adjust the label but the text is "purposeful or conscious")
