Point out the incorrect sentence.
(a) Do not cry over a spoilt milk.
(b) A loaf of bread is more essential than a good deal of advice.
(c) Biscuits are made of wheat-floor.
(d) A blade of grass dances happily in the morning sunlight.
Answer options:

The correct answer is Option B ((a) and (c)).

Key Points:
• Spotting errors involving uncountable nouns and homophones/spelling.
• Option (2) - '(a) and (c)' are the incorrect sentences.
• Sentence (a) is incorrect: 'Milk' is an uncountable material noun and does not take the indefinite article 'a'. The correct standard proverb is 'Do not cry over spilt milk' (without 'a').
• Sentence (c) is incorrect: 'Floor' means the surface of a room; the powdered grain used for baking is spelt 'flour' ('wheat-flour').
• (b) correctly uses partitive nouns: 'A loaf of bread' and 'a good deal of advice'.
• (d) correctly uses the partitive 'A blade of grass'.
• Key Takeaway: Uncountable nouns don't take 'a' (spilt milk), and ground grain is 'flour', not 'floor'.
