statistical information

Explanation:

An almanac can be defined as a publication that is mainly published annually and contains a calendar for the succeeding (upcoming) year, tide tables, farmers' planting dates, phases of the moon, date of eclipses, stated church festivals, feasts, sunrise and sunset times, terms of courts, and other fundamental statistical information such as astronomical data, meteorological data, etc.

This ultimately implies that, an almanac contains statistical information.

For instance, you could consult a farmer's almanac for all the informations regarding the next year's planting schedule (dates), weather forecast, etc. Also, a sport's almanac can be consulted to get all the informations with respect to the upcoming year's game schedule.

quite an interesting way to teach topic sentences, because the answer to this question is the best definition of a topic sentence that one can present, it is as if answering the questions taught you how to do it, this is some real teaching, it is terribly well-done.

the topic sentence in this paragraph is:

topic sentences writers stay on track and keep a paragraph from becoming an aimless collection of sentences about an idea.

which incidentally tells you what a topic sentence should be.
