Which signal word indicates the text structure in the excerpt about a flowering tree?

The choice of "For example" as the signal word indicates a text structure that is typically used to provide illustrations or clarify a point by introducing examples. In an excerpt discussing a flowering tree, this phrase suggests that the text is likely elaborating on specific features, characteristics, or instances related to the tree. When this signal word is present, it usually means that the author will follow with details or specific cases that exemplify the preceding statements.

This contrasts with the other options, which serve different purposes. "Each part" might imply a division of information into segments, which would suggest a sequential or part-to-whole structure. "Distinction" indicates a comparison or contrast, focusing on differences rather than examples. Lastly, "Several" implies a quantity or number, suggesting a listing or grouping but not necessarily the elaboration that comes with providing examples. Each of these alternatives conveys a different organizational intent, but "For example" specifically highlights the exemplary nature of the information being presented.
