I knew what her previous activities were.

Explanation:

• A complex sentence can be formed by inserting one or more dependent (subordinate) clauses into the independent or main clause.

• The addition of dependent clauses can be done with the help of conjunctions or relative pronouns.

• Since the transformed sentence carries an independent clause and a dependent clause, it is a complex sentence. 

(Here we have used the relative pronoun "what")
