A	True
B	False

Explanation:

Detailed explanation-1: -During the long voyage, Darwin made many observations that helped him form his theory of evolution. For example: He visited tropical rainforests and other new habitats where he saw many plants and animals he had never seen before (see Figure below). This impressed him with the great diversity of life.

Detailed explanation-2: -Some types of evidence, such as fossils and similarities between related living organisms, were used by Darwin to develop his theory of natural selection, and are still used today. Others, such as DNA testing, were not available in Darwin’s time, but are used by scientists today to learn more about evolution.

Detailed explanation-3: -After the Beagle returned to England in October 1836, Darwin began reflecting on his observations and experiences, and over the next two years developed the basic outline of his groundbreaking theory of evolution through natural selection.
