<em>Daisy bought two presents for the baby</em> is a simple sentence.
Explanation:
A simple sentence is a sentence consisting of only one independent clause. An independent clause is a clause that can stand on its own, as it contains one predicate and subject and has complete meaning. The sentence <em>Daisy bought two presents for the baby</em> has one subject (<em>Daisy</em>) and one predicate (<em>bought</em>), and has no subordinate clauses. That's why it's a simple sentence.
Compound sentences are sentences consisting of two or more independent clauses that contain related ideas. These independent clauses are connected by semicolons or coordinating conjunctions (for, and, nor, but, or, yet, so).
Complex sentences are sentences consisting of an independent clause and subordinate (dependent) clauses, which don't have a complete meaning and because of that can't stand on their own.
Compound-complex sentences consist of at least two independent clauses and at least one dependent clause.
