A source is something that is used to learn information on a topic. In this case, Andrew needs something that will help him learn about different extinct animals.

Of our answer choices, the best answer is an article that discusses various extinct animals. A chart the includes pictures of extinct animals wouldn't provide enough information to write a report. Also, the report is on more than just one endangered animal; thus, information only on the Bald Eagle would not be as helpful as an article that discusses several endangered animals.

A source is something that is used to learn information on a topic. In this case, Kara needs something that will help her learn about beach vacations. Of our answer choices, the best answer is a book about beaches around the world.

A book that is about popular travel destinations might include some beaches, but there will also be a lot of information that Kara won't need for her report. A book about what sites to see in Paris is not the best choices because Paris is not a place for a beach vacation, and it is only one place and Kara's report will need to talk about multiple beach vacations. Though what to pack for a beach vacation might be included in Kara's report, the main point of the report is about beach vacations in general, so the best answer is a book about beaches around the world.
