Final answer:
The sentence is not a comma splice as it correctly uses a semicolon to separate two independent clauses.
Step-by-step explanation:
The sentence "It was hard to believe; even now" is not a comma splice. A comma splice is a grammatical error that occurs when two independent clauses are joined together with only a comma. In this sentence, the semicolon (;) is correctly used to separate the two independent clauses. The first clause, "It was hard to believe," and the second clause, "even now," are separate ideas, and the semicolon helps to indicate a stronger break than a comma would. Therefore, this sentence does not contain a comma splice.
