Question

testifying in court would be scary.
participle gerund infinitive

Explanation:

To determine the type of the verb form "Testifying" in the sentence "Testifying in court would be scary", we analyze each option:

• A participle is a verb form used as an adjective (e.g., "broken" in "broken glass") or to form verb tenses (e.g., "having eaten" in perfect tenses). "Testifying" here is not acting as an adjective or part of a tense formation.
• A gerund is a verb form ending in -ing that functions as a noun. In the sentence, "Testifying in court" is the subject, which is a noun - like phrase. So "Testifying" is acting as a gerund.
• An infinitive is the base form of a verb with "to" (e.g., "to testify"). "Testifying" does not have "to" and is not in the infinitive form.

Answer:

B. gerund
