Parts of a sentence are given below in jumbled order. Arrange the parts in the correct order to form a meaningful sentence. A. needs to be B. the shelf in C. a piece of wood D. the kitchen E. need to buy F. replaced, so I will

Correct — A. Fix the forced pair first. B, the shelf in, ends on a preposition and needs a place noun, and only D, the kitchen, supplies one. Option (a) is the arrangement that keeps B and D together.

The singular subject then takes A, needs to be, which demands a past participle — F, replaced, so I will.

So I will requires a base verb, E, need to buy, and that verb requires an object, C, a piece of wood.

BDAFEC: The shelf in the kitchen needs to be replaced, so I will need to buy a piece of wood → option (a).

Why the others are wrong

• (b)
  ACDBFE — Puts a piece of wood straight after needs to be, where only a past participle can stand, and finishes on need to buy with nothing left to buy.
• (c)
  DEBACF — Opens the kitchen need to buy, a bare noun phrase followed by a verb with no subject, so the sentence has no grammatical start.
• (d)
  BEFCAD — Breaks the forced pair: the shelf in is followed by need to buy, which leaves the preposition in without the place noun it governs.

Jumbled-parts items are solved by finding forced adjacencies, not by reading each option through from the start.

Three forces operate here. A preposition left hanging, the shelf in, must be followed by its object. A singular subject takes a singular verb, the shelf needs. And needs to be is a passive frame that can be completed by nothing except a past participle, replaced.

Once those pairs are fixed, the coordinator so marks where the second clause begins and the rest falls into place.

Key facts

• A preposition left hanging inside a noun phrase, as in the shelf in, must be followed by the noun it governs.
• Needs to be is completed by a past participle, giving the passive infinitive needs to be replaced.
• After will, the verb takes its base form, which is why the fragment reads will need to buy.

Common traps

• Reading each option end to end instead of testing which fragments must sit together.
• Missing that a singular subject takes needs rather than need.
