The correct answer is 'have lost' because losing keys and still not being able to find them describes a past action with a present result, which is exactly what the Present Perfect tense (have/has + past participle) expresses. The subject 'I' takes 'have' rather than 'has', which is reserved for third-person singular. Present Perfect connects the past to the present without specifying an exact time, unlike Simple Past ('I lost my keys yesterday'), which requires a definite past time reference.

The correct answer is 'has read' because 'already' is a classic signal word for the Present Perfect tense, indicating a completed action relevant to the present moment without stating exactly when it happened. Since 'she' is third-person singular, the auxiliary 'has' is required rather than 'have'. Present Perfect is formed as have/has + past participle and typically pairs with words like 'already', 'yet', 'just', and 'ever', which mark completed actions with present significance.

The correct answer is 'have known' because 'since 2015' indicates an action or state that began in the past and continues into the present, which is precisely what the Present Perfect tense expresses. The plural subject 'we' takes the auxiliary 'have'. The words 'since' (a specific starting point) and 'for' (a duration) are the two key signal words distinguishing Present Perfect usage, as in 'since 2015' versus 'for ten years'. This is one of the most frequently tested tense-signal pairings in exams.

The correct answer is 'have' because the plural subject 'they' requires 'have' rather than 'has' to form the Present Perfect tense with the past participle 'finished'. The word 'just' is a strong Present Perfect signal, indicating an action completed a very short time ago with present relevance. Remember that 'has' is used only with third-person singular subjects (he, she, it), while 'have' pairs with I, you, we, and they in this tense.

The correct answer is 'has' because 'he' is third-person singular, requiring 'has' rather than 'have' to complete the Present Perfect construction with the past participle 'visited'. The word 'never' is a common Present Perfect signal indicating an action that has not occurred at any point up to now. This structure, have/has + never + past participle, is frequently used to describe life experiences, as in 'I have never eaten sushi' or 'She has never been abroad'.

The correct answer is 'had' because the plane's departure happened before another past action (reaching the airport), which requires the Past Perfect tense (had + past participle) to show which of two past events occurred first. Past Perfect is essentially 'the past of the past', clarifying sequence when a story moves between two points in past time. The word 'already' reinforces this earlier-completion sense. Without Past Perfect, a sentence with two past actions can become ambiguous about their order.

The correct answer is 'had finished' because her work was completed before another past event (my arrival), which is exactly what the Past Perfect tense expresses using had + past participle. 'By the time' is a strong signal phrase for Past Perfect, marking a deadline in the past by which an earlier action was already done. This tense helps distinguish which action happened first when narrating two past events, unlike Simple Past which treats events as happening in the order stated.

The correct answer is 'had completed' because 'by 2020' sets a past deadline, and the Past Perfect tense (had + past participle) shows an action finished before that specific past point in time. This mirrors how Future Perfect works with 'by' + a future time, except shifted entirely into the past. Phrases like 'by the time', 'by 2020', or 'before' are reliable Past Perfect signals in exam sentences, helping test-takers spot which past event came first.

The correct answer is 'had' because eating happened before another past action (being invited), and the Past Perfect tense (had + past participle) is used to show that one past event preceded another. The word 'already' strengthens this sense of prior completion. Since 'I' is the subject, 'had' is used regardless of number, as Past Perfect does not change form for singular or plural subjects, unlike Present Perfect's have/has distinction.

The correct answer is 'had' because seeing such heavy rain (or not seeing it) is being compared to another past reference point ('before that day'), requiring the Past Perfect tense (had + past participle) to mark the earlier event. Plural subjects like 'we' still use 'had', since Past Perfect has only one form regardless of subject number. This tense is especially common in narrative writing to establish backstory before the main sequence of past events.
