Here are the correct answers to fill in the blanks. I have checked each one to make sure we use the right form of the adjective (comparative or superlative).
1.
coldest
*(We use "the" and talk about the whole school, so we need the superlative form: cold → coldest)*
2.
better
*(We are comparing two stories using "than". The comparative form of "good" is irregular: good → better)*
3.
fatter
*(We are comparing two sisters. For short words ending in a consonant-vowel-consonant like "fat", we double the last letter: fat → fatter)*
4.
wisest
*(We are talking about "ever reigned," which means all kings in history. We add -st because "wise" already ends in e: wise → wisest)*
5.
thinnest
*(She chose one specific slice out of many. We double the 'n' because "thin" is a short word: thin → thinnest)*
6.
bigger
*(Comparing two twins. We double the 'g' for short words: big → bigger)*
7.
sunniest
*(One of the countries in Europe implies a group. We change the 'y' to 'i' and add -est: sunny → sunniest)*
8.
smaller
*(Comparing two houses using "than". Just add -er: small → smaller)*
9.
longer
*(Comparing tortoises and humans using "than". Just add -er: long → longer)*
10.
richest
*(Asking about the woman on earth implies the number one person. Change 'y' to 'i' and add -est: rich → richest)*
11.
older
*(Comparing Jeremy and Julie. Just add -er: old → older)*
12.
highest
*(Talking about the Alps as a group of mountains. Just add -st because "high" ends in h/g sound often takes simple suffix, but specifically here high → highest)*
13.
easier
*(Comparing this exercise to expectations using "than". Change 'y' to 'i' and add -er: easy → easier)*
