Spotting Errors

Unless is used instead of if + not in conditional sentences of all types. It will use unless with present tense and double future tense should be avoided. Correct phrase is .... Unless he asks me, I shall not help him.

The error is in part (A). This is a Type 2 conditional sentence describing a hypothetical present situation. The if-clause should use simple past 'had', not present 'have'. The correct form is 'If I had an umbrella, I would give it to her' (Type 2) or if referring to a past situation, 'If I had had an umbrella, I would have given it to her' (Type 3). Present 'have' is grammatically incorrect.

The error is in part (B). The phrase 'will have lend' contains two errors: 'will have' is incorrect for Type 2 conditional (should be 'would'), and 'lend' is the base form where past participle 'lent' is needed. The correct sentence should be 'If I had a briefcase, I would lend it to her' (Type 2). The combination 'will have lend' is grammatically incoherent.

The error is in part (A). In Type 2 conditional sentences (hypothetical present/unreal), the verb 'to be' in the if-clause must be 'were' for all subjects, including first person 'I', not 'was'. The correct form is 'If I were you, I would dismiss him from the job'. This is called the subjunctive mood, and 'was' is never correct in formal conditional sentences.

The error is in part (C). In Type 3 conditional sentences (unreal past), the main clause should use 'would have + past participle', not 'can' which is present tense. The correct sentence is 'Had he tried again, he would have passed the examination' or 'could have passed'. Using present modal 'can' with a past conditional is grammatically incorrect.

The error is in part (B). The if-clause uses present continuous ('are looking'), which indicates a real or ongoing situation. This should be followed by 'will find' (first conditional), not 'would find'. The tenses don't match.

The error is in part (A). The sentence uses 'Unless' incorrectly with an imperative structure. It should be 'Don't wait for him unless he comes back' or rephrased entirely. Starting with 'Unless' before 'wait for him' creates a disconnected conditional.

 'Until' is a condition of time and is unsuitable to the context. We need 'unless' here.

Part (A) 'you will heat ice' contains an error. In conditional sentences describing scientific facts or general truths, the if-clause should use present simple, not 'will'. The correct form is 'If you heat ice, it will turn to water'. The use of 'will' in the if-clause is grammatically incorrect.

The article 'The' is incorrectly used before 'dancing' in this context. When using gerunds (verb+ing) to describe an activity, articles are not used. The correct sentence should be 'Dancing is my hobby' or 'I enjoy dancing'. The word 'The' makes it sound like a specific instance rather than the general activity.

 We should always speak "the" truth.

The phrase 'sold by dozen' is grammatically incorrect because 'dozen' requires an article. The correct expression is 'sold by the dozen' (similar to 'by the pound' or 'by the kilogram'). When using 'by' with a unit of measurement, the definite article 'the' is necessary before the unit word.

'as old as' is used only when comparison is being done between two same aged object people and positive degree will be used in this sentence. Since it has a numeral as its predecessor, so the comparison is not correct.  Hence options (A), (C) and (E) can be eliminated directly so the answer is (B)

Organism's cannot be followed by any 'ing' verb, hence (A), (B) and (E) can be eliminated directly; Attempt means to try and both cannot be used together so, (C) is also incorrect.  Hence, the answer is (D)
