4 Summary Choice

The best summary is b.

What is wrong with the other summaries:

• Summary a is partially correct about the relationship when adults, but it overgeneralizes that it is *usually* good.
• Summary c is incorrect because it states the relationship is *usually bad* when they are adults and that people don't change, which is not necessarily true for all siblings.
