Answer:
C) When Maria weaves rugs, she carefully chooses colors that remind her of the desert.
Step-by-step explanation:
The best way to combine both sentences is to create one longer complex sentence, which contains a subordinate clause (When Maria weaves rugs,) and an independent clause (she carefully chooses colors that remind her of the desert). Thus, the meaning of the original sentences is intact. However, the rest of the answer options do not represent exactly the same meaning.
