The correct answer is 'Past Perfect' because 'had left' (had + past participle) shows an action that was completed before another past action occurred, here signaled by 'before I arrived'. This tense is essentially 'the past of the past', used whenever a sentence needs to clarify which of two past events happened first. Past Perfect has a single invariant form, 'had', regardless of subject number, unlike Present Perfect's have/has split. Words like 'before', 'after', and 'by the time' commonly accompany this tense.

The correct answer is 'Past Perfect Continuous' because 'had been working' (had been + verb-ing) emphasizes the duration of an activity that continued up until another point in the past, here reinforced by 'for hours'. This tense merges the earlier-than-another-past-event logic of Past Perfect with the continuous aspect's focus on ongoing duration. It differs from plain Past Perfect, which would simply state 'had worked' without emphasizing how long the action lasted. This tense is invariant in form regardless of subject.

The correct answer is 'Simple Future' because 'will meet' (will + base verb) expresses a straightforward future action or decision, here anchored by 'tomorrow'. This is the most basic and common way to talk about the future in English, used for predictions, promises, and spontaneous decisions. It contrasts with Future Continuous, which would emphasize an action in progress at a specific future time, and Future Perfect, which would mark completion by a deadline. 'Will' does not change form for person or number.

The correct answer is 'Future Continuous' because 'will be traveling' (will be + verb-ing) describes an action that will be in progress at a specific point during a stated future period, here 'next week'. This tense pictures an activity as ongoing rather than a single completed event, much like Present Continuous does for the present moment. It is commonly signaled by phrases indicating a future time frame rather than a precise deadline, distinguishing it from Future Perfect's 'by' constructions.

The correct answer is 'Future Perfect' because 'will have completed' (will have + past participle) marks an action that will already be finished by a stated future deadline, here 'by Monday'. This tense answers the question of what will be done by a certain point in the future, and it is the future counterpart to Past Perfect. Common signal phrases include 'by then', 'by tomorrow', and 'by the time', all pointing to completion relative to a future reference point rather than ongoing activity.

The correct answer is 'already' because it is one of the classic signal words for the Present Perfect tense, indicating that an action has been completed at an unspecified time before now, with continuing relevance to the present. Other common Present Perfect markers include 'yet', 'just', 'ever', and 'never'. In contrast, 'yesterday' and other specific time expressions require Simple Past, while 'now' and 'tomorrow' point toward continuous and future tenses respectively, making precise time-marker recognition essential for tense questions.

The correct answer is 'ago' because it always refers to a specific point measured backward from now, such as 'two years ago' or 'a moment ago', which requires the Simple Past tense to state a completed action at that definite time. This distinguishes 'ago' from 'since', which marks a starting point used with Present Perfect, and from 'already' and 'yet', which are also Present Perfect signals. Exam questions frequently pair 'ago' with Simple Past to test whether students confuse it with 'for' or 'since'.

The correct answer is 'since' because it marks the starting point of an action that began in the past and continues into the present, which is the hallmark structure of the Present Perfect Continuous tense (have/has been + verb-ing). This contrasts with 'for', which expresses duration rather than a starting point, though both commonly accompany this tense. Time markers like 'last week', 'tomorrow', and 'yesterday' instead belong to Simple Past or future tense contexts, making 'since' the clear choice here.

The correct answer is 'The earth revolves around the sun' because it states a permanent scientific fact using the Simple Present tense, which is the standard tense for laws of nature and universal truths regardless of when the sentence is spoken. The singular subject 'earth' takes the third-person -s ending on the verb. The other options wrongly use future, continuous, or past forms, which would incorrectly suggest the fact is a one-time, ongoing, or completed event rather than an eternal truth.

The correct answer is 'I have finished my work' because it correctly uses the Present Perfect structure (have/has + past participle) with the first-person subject 'I' taking 'have'. This tense expresses a completed action with present relevance, without specifying exactly when it was finished. The distractor options incorrectly use future ('will finish'), continuous ('am finishing'), or simple present ('finish') forms, none of which match the completed-with-present-relevance meaning that Present Perfect conveys.
