Answer:
C
Step-by-step explanation:
In order to determine which detail would be most important to include in a summary of the passage, we need to consider the overall focus and main point of the passage.
Option A states that a used Band-Aid should not be kept for future use. While this detail may be important in a different context, it is not directly related to the main point of the passage.
Option B mentions that psychologists know how to help people who hoard. While this is a valuable piece of information, it does not provide the most important detail to include in a summary of the passage.
Option D states that some people enjoy collecting things such as books, music, or stamps. This detail is interesting, but it does not address the main point of the passage.
The most important detail to include in a summary of the passage is option C, which states that hoarders are attached to objects that most people can easily get rid of. This detail directly addresses the main point of the passage, which is the attachment hoarders have to objects that others find disposable.
Therefore, the most important detail to include in a summary of the passage is that hoarders are attached to objects that most people can easily get rid of.
