Synthesis of Sentences — Important Questions

Adjective clause

Adjective clauses begin with relative pronouns like 'who', 'which', 'where', 'that', 'whom', 'whose'. These clauses describe or give more information about nouns, just like adjectives do. For example: 'The house where I grew up' - 'where I grew up' describes 'house'. Noun clauses begin with words like 'that', 'what', 'how'. Adverb clauses begin with words like 'because', 'when', 'if'.

to

This is an example of synthesis using an infinitive. 'To buy' is an infinitive (to + base form of verb) that shows purpose. The original sentences were 'We have to go to the market' and 'We will buy vegetables'. The infinitive 'to buy' efficiently combines these ideas. 'For', 'and', and 'because' would create different sentence structures but not the intended infinitive construction.

Using a noun in apposition

Apposition means placing a noun or noun phrase next to another noun to explain or identify it. 'My favourite city' is in apposition to 'Mumbai' - both refer to the same thing. The original sentences were 'Mumbai is my favourite city' and 'It is very crowded'. The phrase 'my favourite city' is set off by commas and renames Mumbai. This is not an adjective, adverb, or participle construction.

for

'For' is used as a coordinating conjunction to show reason or cause in compound sentences. Example: 'Rana went upstairs for it was his bedtime' - 'for' explains why he went upstairs. 'But' shows contrast, 'or' shows choice/alternative, and 'yet' shows contrast despite expectation. Only 'for' indicates the reason behind an action.
