Understanding the of a text is an integral part of analyzing it.
a.
subheadings
b.
organization
c.
annotation
d.
synthesis

The correct option is B: ORGANIZATION

Explanation:

Before thinking about the options that have been given to us we have to remember that most texts share some features, between them there are:

Now that we know three features that most of the texts have we can think in the different types of texts that exist:

1. Narrative texts

2. Descriptive texts

3. Argumentative texts

4. Expositive texts

5. Scientific texts

Finally, the answer that we have to answer is option B: ORGANIZATION because, as we have seen, every kind of text has its features, so knowing it everything will be easier for us at the moment of understanding it. Option A: SUBHEADINGS cannot be the correct one because, in some way, the presence or absence of subheadings responds to the structure organization and its respective theme, but in a restrictive way. Option C: ANNOTATION is not the one because annotations are just a minimum part of the text that adds extra information, so they are not strictly related to the main topic; and finally option D: SYNTHESIS is wrong because not all the texts types have a synthesis part, as we saw, it depends on the kind of text that we have and the purposes that it follows.

i believe the answer is d
