What's That Big Tree in The Little Prince?

The exam will consist of multiple-choice questions centering on the subject of plants and culture. Questions will relate to plant names, as well as the role plants play in such areas as science, the environment, cooking, language, art, music, and literature, some focusing on just one of these areas and others mixing two or more. Some of the questions will test one's knowledge of plants that appear in works of literature, like the following:

What is the name of the large tree, known to grow in savannas, that is mentioned in the novel Little Prince by Antoine De Saint-Exupery? (Answer: baobab)
Others will deal with the symbiotic relationship between plants and animals:

It appears that, to achieve a high score, examinees will need to know not only their flora, but a wide range of other topics as well.
