simple, compound, complex, or complound-complex?

Question

^ which one for each sentence?
1. one of the most common problems that beginners face is lack of cordination; another is muscular aches and pains.
2. at the same time, coordination grows with confidence.
3. as a rule, learning something new takes time and work, or it will not seem worthwhile.
4. in sports, as in most other activities, persistance and patience often pay off.

Answer 1

A simple sentence has one independent clause, and no dependent clauses., or

A complex sentence has a dependent and an independent clause.

A compound sentence has two independent clauses.

A compound complex had two independent clauses and at least one dependent clause.

In your examples:

1. is a compound sentence because there are two independent clauses. a hint to seeing this is the semi-colon. A semicolon separates two independent clauses.

2. this is a complex sentence, the dependent clause is at the same time, the independent clause is coordination grows with confidence. Here, if you have a clause separated by just a comma, then you have a dependent clause.

3. This sentence is compound and complex. the independent clauses are separated by a comma and a conjunction (the ,or). the dependent clause is "as a rule"

4. this is a complex sentence. It has two dependent clauses: "in sports" and "as in most other activities"... the independent clause is "persistence and patience often pay off"

i hope this helps
