Which of the following is an example of a question using the present perfect tense?

The present perfect tense is used to indicate an action that occurred at some indefinite point in the past or that has relevance to the present moment. In this case, the phrase "Have you ever traveled abroad?" is in the present perfect tense because it uses the auxiliary verb "have" along with the past participle "traveled." This structure implies that at some point in the person's life up to now, they might have had the experience of traveling abroad, which connects the past experience with the current moment.

The other options reflect different tenses. For instance, "Did you travel last year?" is in the simple past tense, referring specifically to a completed action in the past without any connection to the present. Similarly, "Are you traveling next week?" is in the present continuous tense, indicating a future arrangement, while "Will you travel someday?" uses the simple future tense to discuss a potential action in the future. None of these choices express a relationship between the past and the present in the way that the present perfect tense does.
