D will come after a to form the phrase ‘cross my mind’. If you say that an idea or possibility crossed your mind, you mean that you thought of it. Only options D and E have AD in their final sequence. The rest can be negated.

Part B begins with ‘and’, which means this is the start of a second clause. C will come after B. This way, the first part mentions the suspicion of the speaker and the second part confirms it. This leaves E to come in between AD & BC.

B will follow A to form the phrase ‘came across’. Here, to come across means to hand over or provide what is wanted. The sentence mentions robber and pistol, so naturally she will give all her money. This story is conveyed if we place E after AB.

D will follow C as the robber taking out his pistol and pointing at her head will compel her to give all the money. The sequence becomes CDABE. Hence, the correct answer is B.

When the reporting verb ‘asked’ is in the past tense as in the first part of the given sentence, the verb in the reported speech ‘can’ as in the third part of the sentence also has to be in the past tense. Thus, C is the correct answer
The correct sentence would be :

When asked about the ailments plaguing the elderly, doctors at the All India Institute of Medical Sciences (AIIMS) said that 75% of problems in old age could be attributed to osteoporosis. 

The use of the adverb 'when' in part (II) of the given sentence is incorrect. Instead of the adverb ‘when’, which denotes time, an adverb for place needs to be used like ‘where’.
So, the correct answer is option C.

The error in part I of the sentence is that the noun ‘sceneries’ is used in the wrong count. It should be ‘scenery’ and this does not have a plural form. Again, in part III of the sentence, ‘participate’ has been used in the wrong tense. The sentence is in past perfect tense and ‘participated’ should be used. Thus, D is the correct answer.

The errors are in parts I and III. In I, instead of the verb ‘Knighted’ we need an adjective to describe the stone effigy. So, it should be ‘knightly’ which means associated with or typical of a knight; chivalrous. Also, in part III, the use of the word ‘stonely’ is absurd. It should be ‘stone’ to describe the make of the cartoon strip.

The error in part I of the sentence is that the preposition ‘in’ is incorrect. You can either take ‘stand on’ something or ‘stand for’ something. The error in part II of the sentence is that the preposition ‘of’ is incorrect. Once can only demand ‘for’ something, not ‘of’ something. Hence, option B is the right response.

The error in the emboldened part of the sentence lies in the wrong use of the adjective ‘intentional’. To be contextually correct, the noun form, ‘intention’, needs to be used.
Thus, option D is the correct answer.

The error in the emboldened part lies in the wrong usage of the adverb, ‘there’. Given the context of the sentence, the correct word is the pronoun ‘their’, reflecting back to the pronoun, ‘they’ and ‘them’.
Thus, option A is the correct answer.

The error in the emboldened part lies in the use of the verb ‘resign’, instead of the noun, ‘resignation’. And the correct phrasal verb is 'hand in', which means to give something to a teacher, police officer, or other person in authority.
