Parts of a sentence are given below in jumbled order. Select the option that arranges the parts in the correct sequence to form a meaningful sentence. (P) dreams provide an escape (Q) where reality is suspended (R) into a world (O) of endless possibilities

Correct — C. P is the only part that can stand as a main clause — dreams provide an escape — so it opens the sentence.

Escape takes the preposition into, which is how R begins, so R follows P: an escape into a world.

O is an of-phrase and modifies the noun in front of it — a world of endless possibilities.

Q has a subject and a verb too, but where subordinates it to a noun, and that noun is world, so Q closes the sentence. P-R-O-Q, option (c).

Why the others are wrong

• (a)
  QORP — QORP opens on where reality is suspended, a relative clause with no noun in front of it to modify. Its antecedent, world, has not been mentioned yet.
• (b)
  OPQR — OPQR starts on of endless possibilities, a bare of-phrase. An of-phrase modifies the noun immediately before it, and there is none.
• (d)
  RPOQ — RPOQ starts on into a world, a preposition phrase with no verb in front of it to attach to. The verb it belongs with, provide an escape, arrives only in the next part.

A four-part jumble is a grammar exercise in a comprehension costume. Three tests place most parts.

Main clause first. The part that can stand on its own as a sentence is the spine. A part whose verb sits inside a where- or which-clause does not qualify, however complete it looks.

Prepositions point backwards. A part beginning into, of or with must sit right after the word that governs it — escape into, world of.

Relative words need an antecedent. Where, which and who must follow the noun they describe, so a part beginning where cannot open a sentence.

Key facts

• Escape as a noun takes into for the place escaped to: an escape into a world.
• An of-phrase modifies the noun immediately before it, which is why O must follow R.
• Where introduces a relative clause and needs its noun to have appeared already.

Common traps

• Choosing RPOQ because into a world sounds like an opening phrase.
• Starting with Q or O, both of which are fragments that need a noun before them.
