Sentence arrangement (reordering words): form a past-tense sentence about sudden departure Numbers correspond to words; reorder them into a correct sentence: 1 = "left" 2 = "the" 3 = "house" 4 = "he" 5 = "suddenly" Choose the correct sequence of numbers to form the sentence.

Given data

• Tokens: left / the / house / he / suddenly.

Concept/ApproachCanonical order: Subject → Verb → Object → Adverbial. The subject pronoun “he” should lead the sentence; the noun phrase is “the house.” An adverb of manner (“suddenly”) is naturally placed at the end.

Step-by-step arrangement4 (“he”) → 1 (“left”) → 2 + 3 (“the house”) → 5 (“suddenly”)Sequence = 41235

Common pitfalls

• Beginning with “left” (verb) and delaying the subject, which is ungrammatical in a neutral declarative sentence.
