Question

which sentence from passage 3 provides evidence that certain objects produce a particular pattern of brain activity regardless of whether they were seen while awake or asleep? neuroscientists like tong and those who conducted the new study want to understand how our brains produce the images we see in a dream. (paragraph 4) previous experiments on mice have helped scientists understand some aspects of dreaming, such as how memories are formed. (paragraph 5) over and over, the volunteers fell asleep for a short while before being woken up and asked to describe their dreams. (paragraph 9) more often than not, the program correctly picked which of two objects had appeared in a dream—for example, a girl and not a book. (paragraph 11)

Explanation:

The question asks for evidence that certain objects produce a particular pattern of brain activity regardless of whether they were seen awake or asleep.

• Option 1: Just mentions neuroscientists' goal of understanding brain - produced dream images, no relation to object - specific brain activity patterns in awake/asleep states.
• Option 2: Talks about mice experiments and memory formation in dreaming, not about object - specific brain activity.
• Option 3: Describes an experiment procedure (volunteers sleeping and being woken), no information about object - related brain activity.
• Option 4: The program correctly identifying objects in dreams (e.g., a girl vs a book) implies that there are distinct, object - specific brain activity patterns that can be detected whether the object was seen in a dream (asleep) or in reality (awake).

Answer:

The fourth option: "More often than not, the program correctly picked which of two objects had appeared in a dream—for example, a girl and not a book. (paragraph 11)"
