To determine which evidence from the text best supports the answer to part A, we would need to first clarify what part A specifically addressed. Since that context is missing, I can provide guidance based on the statements you've provided:
-
If part A discusses the mental abilities of Azy and how he demonstrates understanding or learning, option C ("maybe this can teach us a little bit about how he thinks") might be the most relevant as it directly relates to insights about his thought processes and cognitive abilities.
-
If part A focuses on Azy's performance in learning or scoring, option B ("Azy, a 21-year-old male orangutan, had been scoring 100 percent on the day vocabulary test until now") might be most relevant, as it highlights his previous success in vocabulary tests.
-
If part A discusses the broader context of orangutans and their mental abilities, option D ("orangs' mental abilities are the least understood of the great apes, notes the biologist") could be suitable as it places Azy's abilities within the larger framework of what is known about orangutans.
-
Option A ("Azy lifts his long, graceful hand and points to the symbol for cup") describes a specific action that could illustrate Azy’s ability to communicate or comprehend symbols, making it relevant if part A concerns his ability to represent ideas.
Without knowing the answer to part A, I would suggest selecting the option that best aligns with the focus of your answer in part A.
