Fill in the blank with the correctly spelt word. The new theory was dismissed as ________ by the mainstream scientific community.
- (a)prepostrous
- (b)preposterous
- (c)preposturous
- (d)preposteruos
Answer
Why
Correct — B. The blank follows dismissed as, so it holds the verdict on the theory. All four options aim at one word, preposterous: absurd, contrary to reason.
Spell it by syllables: pre-pos-ter-ous. The Latin source, praeposterus, means 'before-behind', putting last what should come first.
Preposterous is the option with both the -ter- and the -ous intact → option (b).
Why the others are wrong
- (a)prepostrous — Prepostrous drops the e of -ter-, leaving three written syllables. Said quickly the word can sound like that, but the spelling keeps all four: pre-pos-ter-ous.
- (c)preposturous — Preposturous writes the third syllable as -tur-, as in posture. The root is Latin posterus, 'coming after', so the spelling keeps -ter-.
- (d)preposteruos — Preposteruos swaps the last two vowels of the ending. The adjective suffix is -ous, as in famous and dangerous.
Concept
A correctly-spelt fill-in has two layers. The sentence fixes the meaning, and here every option is an attempt at the same word, so the item is decided on spelling alone.
Break a long word into syllables and check each one: pre / pos / ter / ous. Each wrong option damages one part: an e is dropped from the third syllable, the third syllable is respelt, or the ending is scrambled.
The root anchors the tricky middle: Latin posterus, 'coming after', also gives English posterity and posterior.
'Dismissed as' is followed by the verdict, an adjective or a noun: dismissed as preposterous, dismissed as nonsense. The sentence settles the meaning; the options differ in spelling alone.
Key facts
- Preposterous means contrary to reason or common sense, utterly absurd.
- It comes from Latin praeposterus, literally 'before-behind': prae, 'before', + posterus, 'coming after'.
- Syllable by syllable it is pre-pos-ter-ous.
- Posterity and posterior come from the same Latin posterus.

Common traps
- Spelling the word as it can sound in quick speech, pre-pos-trous, and losing the e of -ter-
- Letting posture pull the third syllable to -tur-
- Checking only the start of each option: all four begin prepos-, and the errors sit in the last two syllables
