Step-by-step explanation:
1.
1 - D. Two or more independent clauses and one or more dependent clauses - Compound-Complex Sentence.
2 - C. One independent clause and one or more dependent clauses - Complex Sentence.
3 - A. The sentence with only one independent clause (one complete thought - Simple Sentence.
4 - B. Two or more simple sentences that are joined by coordinate conjunction, punctuation, or both - Compound Sentence.
2.
This sentence is simple. The cat crawled under the table to hide. As it has just one independent clause or one complete thought. It has one subject, one verb, and modifiers.
3.
Although it rained for three hours, the coach did not cancel baseball practice.
It is a complex sentence. It has one independent clause (the coach did not cancel baseball practice - one complete thought, it can be a separate sentence) and one dependent clause (Although it rained for three hours - it doesn't have a complete thought, it depends on the other part of the sentence).
4.
Mom baked cookies for the school picnic, and Dad volunteered to grill the hamburgers.
It is a compound sentence these two sentences are independent, they can stand alone, and they are joined by coordinating conjunction 'and'.
5.
After Molly lost the student council election, she decided to try out for soccer, and her friends thought she made a good decision.
It is a complex compound sentence. It has two independent clauses that can stand on their own without losing a complete thought (1: she decided to try out for soccer, 2: her friends thought she made a good decision), and one dependent clause (After Molly lost the student council election), it can't stand alone.
6.
The best way to combine these two sentences (The cat walked. The cat purred.) --->> The cat walked and purred. Because these sentences have one subject, the same cat walked and purred, so it is better to connect them with the conjunction 'and'.
7.
The most effective way to combine the following two sentences: Allison drank all the milk. She went to the store to buy another gallon --->> Since Allison drank all the milk, she went to the store to buy another gallon.
These two sentences became a complex sentence with the help of the word 'since'. It has one independent clause - a complete thought (she went to the store to buy another gallon), and one dependent clause (Since Allison drank all the milk). This dependent clause explains to us why happened the main clause.
