Answer:
1). a. Compound sentence
2). a. A word or group of words that renames a noun
3). a. add -'s to the noun.
4). a. to indicate when someone is speaking
Step-by-step explanation:
1). Compound sentences are defined as the sentences that consist of a minimum of two independent clauses conveying complete sense. These two clauses are joined using a comma(,), semicolon(;), or coordinating conjunction. Since the given sentence is a compound sentence joined using a conjunction ('for'), the comma rule followed would be 'compound sentence' as it separates the one independent idea from the other.
2). Appositives are defined as the word of a group of words which is the explanatory equivalent of a noun or a noun phrase in a sentence. Both the appositive and the noun possess the same syntactic function in the sentence. Thus, it functions to rename a noun or noun phrase.
3). Ownership or possession in the case of a singular noun is showed using an apostrophe(') followed by s, no matter if the word ends with the letter s or not. Apostrophe only is used to denote a plural noun ending with the letter s. Thus, option A is the correct answer.
4). Quotation marks are used for a variety of purposes. One of them is to quote the exact words used by the speaker in his/her speech during a conversation. Thus, it indicates the exact dialogue of the person who was speaking or is speaking. Hence, option A is the correct answer.
