Question

First, storm clouds form a narrow line, called a squall line, which creates violent weather a. Compound b. Complex c. Compound complex

Answer 1

None of these are correct.

Step-by-step explanation:

I am guessing they are looking for B. to be the answer, but in order to do that, you must have a subordinating conjunction such as "Because, When, Before, After" which then starts a complete sentence. It most definitely is not A or C, because in order to be compound, it must include a coordinating conjunction. (but, and, for, nor, or, so, yet).

Answer 2

b. Complex

Step-by-step explanation:

Complex phrases are those in which an independent clause can be observed associated with a dependent clause or more than one.

Independent clauses are those that can be expressed on their own and make complete sense. However, the dependent clauses do not make sense on their own and need to be complemented.

The independent clause of the question above is "First, storm clouds form a narrow line, called a squall line", the dependent clause is "which creates violent weather".
