Correct the given sentence gramatically.

Shreya, who she is my best friend, is a singer.

‘Out of’ is the incorrect preposition used in the sentence. ‘Of’ needs to be used as the correct form of preposition is ‘made of something’. Thus, the correct sentence would be, ‘The jug is made of clay’.

‘Poetry’ needs to be replaced with ‘Poem’ to make the sentence contextually correct. ‘Poetry’ is a literary work; ‘Poem’ is a piece of writing. Here, the writing is being talked about. Thus, the correct sentence would be, ‘The writer of this poem is Wordsworth’.

‘Prefer’ is followed by the gerund form of the verb. Thus, ‘spend’ needs to be replaced with ‘spending’ to make the sentence grammatically correct. Thus, the correct sentence would be, ‘Though he is a gifted comedian, he prefers spending his spare time watching horror movies.

‘Cured’ is followed by the preposition ‘of’. Thus, the correct sentence would be, ‘He will be cured of his fever’.

The modal ‘Could’ is used to express possibility. It is simply used to state one or more things that are possible or were possible in the past. In this statement, ‘to have achieved’ needs to be replaced with ‘for achieving’ to make the sentence correct. Thus, the correct sentence would be, ‘When I finished writing the letter, I could not help admiring myself for achieving the impossible’.

With certain words like, be senior to, be junior to, be superior to, be inferior to, etc. is always followed by ‘to’. Thus, the correct sentence would be, ‘I am senior to him by two years’.

Since, the starting statement carries a subject; R will be the first statement as it talked about sense of inferiority. S follows next logically. P describes the feeling of inferiority and thus continues with the flow. Q will be the concluding statement and thus form a coherent paragraph.

The correct formation would be, ‘The sense of inferiority in others and not an exalting one is a painful feeling without this indirect appeal of our self-love.’
