Q1.
I. Complete the sentences by filling in the noun form of the textual words given in the brackets.
1. Some word games need a lot of thought and _________________. (deduce)
Answer
Some word games need a lot of thought and deduction.
How the noun is formed: deduce → deduction. Verbs ending in -duce drop the -ce and take -ction: produce → production, reduce → reduction, introduce → introduction. Learn the family, not the single word.
Tip: Deduction has a second, quite separate meaning — an amount subtracted, as in “a deduction from his salary”. Context decides which one is meant.
