Answer:
1. Simple
2. Complex
3. Compound
Step-by-step explanation:
A simple sentence is one that consists of only one chasuble, which alone can be coherent enough and understandable, like sentence number 1, shown in the question above.
A complex sentence is one that has two clauses that do not have a dependency relationship with each other, that is, the sentences manage to maintain their meanings alone, like sentence number 2, shown in the question above.
A compound phrase is one that has two clauses, but one cannot have meaning alone, while the other does. So this type of sentence has a dependent clause and an independent clause, like sentence number 3.
