Advanced Level Grammar Exercise – MCQ Test 20

Both actions are finished past events that happened at the same time, so both verbs take the past simple: originated and began. Not had originated / began: the past perfect would put the start of tourism before the middle classes began travelling, but the sentence says it happened when they began.

For almost an hour shows an action that continued up to a point in the past, so the first gap needs the past perfect continuous: had been lying. The second action interrupts it and the hunter receives the action, so it needs the past simple passive: was spotted. Not was lying / spotted: spotted is active, but the hunter did not spot anyone; he was spotted.

The sentence describes one specific success in the past. For a single past achievement we use was/were able to (or managed to), not could. Not could have knocked: this means it was possible but did not happen, which does not fit an event that really took place.

If (they are) detected is a reduced conditional clause: the diseases can be treated successfully on condition that they are found early. Not unless: it means 'if not', which reverses the meaning.

While can mean 'although' and introduces a contrast between two clauses: some progress has been made, but it is not enough. Not Despite: it is a preposition and must be followed by a noun or -ing form (Despite making minimal progress…), not by a full clause.

Some is used with plural countable nouns (some interacting processes), and the relative pronoun that is the subject of bring: processes that bring materials together. Not by which: it cannot be the subject of the verb bring.

Anything (that) I can do means 'everything possible', with the relative pronoun left out. After help someone we use the bare infinitive (or to-infinitive): help you overcome. Not whatever / overcoming: help you overcoming is not correct.

The gap introduces an indirect question about the cause, so we need why: Adam didn't tell me why he didn't like me. Not the reason of: we say the reason (why/that) he… or the reason for something, never the reason of + clause.

Patience is uncountable, so it takes enough or much, not many. In the second gap, as much means 'the same amount (of patience)': she didn't have as much before she had her own children. Not too many / any: many cannot be used with an uncountable noun.

This is a second conditional about an imaginary present or future situation: If + past simple (here passive, were given), would + base verb (would pick). Not had been given / might pick: a past perfect if-clause needs would/might have + past participle in the main clause.

The pattern is allow someone to do something, so we need allowed Peter to develop. The past simple fits a completed achievement. Not allow / developing: allow is not followed by an object + -ing form here, and the singular subject a combination would need allows anyway.

Both events are finished past actions, and on Tuesday is a specific past time, so we use the past simple: created and the passive was granted (the scientist received the licence). Not has created / has been granted: the present perfect cannot be used with a finished time expression like on Tuesday.

By next week means 'at some time before next week', which calls for the future perfect: will have left. Not is leaving: the present continuous describes a fixed arrangement at a time (on Monday), but it does not combine naturally with by + a future time.

Every time is a conjunction meaning 'whenever', and it introduces a clause about a repeated situation. The question reporters ask is How do you like Istanbul?, reported as how they like Istanbul. Not During / whether: during is a preposition and cannot be followed by a clause.

Have yet to + verb means 'have not done something so far': the results have yet to be announced = they haven't been announced. Another week means 'one more week'. Not still: have still to is possible, but each week does not make sense in the second gap.

Nor adds a second negative idea after a negative one (failed to get anyone) and is followed by inversion: nor could she do it. Not so: so could she adds a positive idea, which does not match the negative first clause.

Be known + to-infinitive reports a generally accepted fact: is known to vary. The second gap is a participle clause showing the result of the first: …, leading to hot and cold regions. Not to be varying / to lead: the continuous infinitive is unnecessary for a general fact, and a to-infinitive cannot express a result in this position.

Anyone so intelligent means 'anyone as intelligent as that', and that stupid mistake refers to the specific mistake he made. Not too / such: too intelligent to would need a different structure, and such needs an article before a singular noun (such a stupid mistake).

With I don't suppose / I don't think + clause, the tag follows the verb in the second clause, not I suppose. Because the negative of suppose really belongs to that clause (= you aren't telling us…), the tag is positive: are you? Not do I: tags are not formed with I suppose / I think.

Such as introduces examples: relaxation techniques such as yoga and meditation. Not just as: it is used for comparison (just as effective as), not for giving examples.
