A claim
The sentence that contains the expression "all men are created equal" is a claim that needs to be justified or proven with reason and evidence. This is not a universal truth and is not experienced by many; thus, the author must prove his point or claim.
The situation wherein you would double the final consonant in a base word before adding a suffix is option D. When the base word ends with consonant + vowel + consonant and the suffix begins with a vowel. For example: the word, "FAT" when we add the suffix -er and -est, it becomes "fatter" and "fattest". The letter "T" is doubled, then add the vowel suffix.
Here's some examples I came up with:
- Though some people are considered living and breathing, they aren't truly alive at all.
- There are many ways to show someone you're truly apologetic.
- If you've got nothing nice to say, don't say anything at all.
- There's nothing like a good book and some snacks.
Hope I helped! :)
