Question

Change the degree of comparison from superlative to comparative without changing the meaning:
Australia is the greenest island in the world.

• A. No other island in the world is as green as Australia.
• B. Australia is greener than all other islands in the world.
• C. None of the options
• D. Australia is more greener than all other islands in the world.

Answer 1

Answer: (B)

Australia is greener than all other islands in the world.

An adjective can exist in three forms-positive, comparative and superlative. The positive form is the base form of the adjective. The comparative form expresses a higher degree of some quality. The superlative form expresses the highest degree. For adjectives with three syllables or more, the comparative degree is formed using the word 'more' and the superlative degree, using the word, 'most'.
Option B is correct as 'greener' is the comparative form of 'green'.
Option A is incorrect as 'green' is the base form.
Option C is obviously incorrect as Option B is correct.
Option D is incorrect as we don't use a double comparative structure. 'More' and "greener' are both comparative in form, so it is avoided.
