Answer the following questions in one word: a) What is the past participle of ‘write’? b) Which word is a conjunction: ‘but’, ‘how’, or ‘the’? c) What is the plural form of ‘child’?

a) written – the past participle of ‘write’.
b) but – a coordinating conjunction that introduces contrast.
c) children – the irregular plural of ‘child’.

The past participle is used with auxiliary verbs to form perfect tenses. The conjunction ‘but’ connects opposing ideas, while ‘how’ asks about manner and ‘the’ is a determiner. The noun ‘child’ has an irregular plural form ‘children’, unlike regular nouns that add –s.
