Guys can someone explain to me what is compound and complex sentences like I'm a 5 year old girl? I mean a really good explanation and with examples please.

A compound sentence is a sentence that has at least two independent clauses joined by a comma, semicolon or conjunction.

An example of a compound sentence is:

This house is too expensive, and that house is too small.'

Mary doesn't like cartoons because they are loud, so she doesn't watch them.

A complex sentence is a sentence that contains an independent clause and one or more dependent clauses.

An example of a complex sentence is:

   Because my coffee was too cold, I heated it in the microwave.

   Although he was wealthy, he was still unhappy.

   She returned the computer after she noticed it was damaged.

   Whenever prices goes up, customers buy less products.

the answer is #2 if im not mistaken
