Final Answer:
The group of words in bold, "an annual publication that includes long-range weather predictions," is a clause.Thus the correct option is option 2.
Step-by-step explanation:
A clause is a group of words that contains a subject and a verb and can function as a complete sentence or as part of a sentence. In this case, "an annual publication that includes long-range weather predictions" contains a subject ("an annual publication") and a verb ("includes"), making it a clause. It provides additional information about the farmers' almanac and acts as an integral part of the sentence.
Moreover, this clause functions within the sentence as a modifier, providing descriptive details about the farmers' almanac. It gives more information about the nature and content of the almanac, specifying its purpose and the methods used for calculating forecasts. As a clause, it enhances the sentence's meaning by adding essential details rather than functioning as an independent phrase that lacks a subject and a verb.
