An intergalactic pet show judge is comparing two alien creatures: a Zorg and a Blip. Select ALL the sentences that use comparative adjectives correctly!
The correct answers are The Zorg is heavier than the Blip. and The Zorg is bigger than the Blip.
Heavier correctly applies the rule for two-syllable adjectives ending in "-y" (heavy → heavier).
Bigger correctly doubles the final consonant for short, one-syllable adjectives ending in a consonant-vowel-consonant (CVC) pattern (big → bigger).
"Intelligenter" is incorrect because intelligent has four syllables and must use "more" (more intelligent).
"More big" is incorrect because big is a one-syllable adjective and must take the "-er" suffix (bigger).
