A simple sentence has only one clause.
A complex sentence has one main clause and one or more subordinate clauses.
A compound sentence has two or more clauses of the equal rank.
State whether the following sentences are simple, complex or compound.

The correct answer is "Complex sentence" because "who spoke English" is a subordinate relative clause.
2I have been on rather too many planes and trains recently.
Wrong!
The correct answer is "Simple sentence" because the sentence has one independent clause.
3We drove right up to Helsinki in two days.
Wrong!
The correct answer is "Simple sentence" because the sentence has one independent clause.
4I don’t care how expensive it is.

The correct answer is "Complex sentence" because "how expensive it is" is a subordinate noun clause.

The correct answer is "Simple sentence" because the sentence has one independent clause.
7I guess she just doesn’t respect you.
Wrong!

Wrong!
The correct answer is "Compound sentence" because two independent clauses are joined by "and".
9You can either come with me now or walk home.
