1. When two main clauses are joined together without the use of a coordinating conjunction, they should be separated by a semicolon.

To determine the correct answer for this question, you need to understand the concept of coordinating conjunctions and how main clauses can be joined together. Coordinating conjunctions are words like "and," "but," "or," "yet," "so," and "for" that are used to connect two main clauses. However, if you want to join two main clauses without using a coordinating conjunction, a semicolon is used as the punctuation mark to separate them.

Therefore, the answer to the first question is A. semicolon.

2. Choose the proper punctuation to fill the blank(s) in the sentence "Maria cares about just one thing ________ money."

To answer this question, you need to consider the purpose and meaning of the sentence and choose the punctuation mark that correctly fits in the blank space.

In the given sentence, the phrase "Maria cares about just one thing" introduces a complete thought or statement. The blank space is meant to link this introductory phrase to the object, which is "money."

In this case, a colon (:) is the appropriate punctuation mark to use because it indicates that what follows the colon is an explanation or elaboration of what comes before it.

Therefore, the answer to the second question is C. colon.
