Final answer:
Joshua wants to create a A)compound sentence by joining two independent clauses using a coordinating conjunction. These sentences provide equal importance to both clauses and often use conjunctions like 'for, and, nor, but, or, yet, so' to connect them.
Step-by-step explanation:
The type of sentence that Joshua wants to add to his essay, which joins two independent clauses using a coordinating conjunction, is called a compound sentence. In a compound sentence, the independent clauses are of equal importance and are joined together with a coordinating conjunction such as for, and, nor, but, or, yet, or so. An example of a compound sentence is 'This peach is way beyond ripe, and I refuse to pay for it,' where 'and' is the coordinating conjunction joining the two independent clauses.
