Parts of a sentence are given below in jumbled order. Arrange the parts in the correct order to form a meaningful sentence. (a) the use of animal research (b) throughout the past century (c) and it continues to be used to understand many diseases (d) has been of considerable importance (e) in the field of scientific and medical advancements

Correct — D. Build the sentence first, then match it against the strings.

Part (a), the use of animal research, is the only part that can be the subject; part (d), has been of considerable importance, is the finite verb that agrees with it. Part (e) then says in what field and part (b) over what period.

Part (c) opens with and, so it can only close the sentence:

the use of animal research has been of considerable importance in the field of scientific and medical advancements throughout the past century, and it continues to be used to understand many diseases.

That is adebc — option (d).

Why the others are wrong

• (a)
  edcba — edcba puts the verb part (d) second with no subject in front of it, and strands the subject part (a) at the very end, behind the and-clause.
• (b)
  aecdb — aecdb drops the and-clause, part (c), between the subject part (a) and its verb part (d), so a coordinated clause interrupts a sentence that has not yet reached a verb.
• (c)
  ecdba — ecdba opens on a prepositional fragment and asserts the and-clause before anything has been said; the verb part (d) then arrives with its subject part (a) left until last.

A five-part jumble is solved on structure, not by reading the four strings end to end.

Find the part that can only be the subject — here the single noun phrase with no preposition, conjunction or verb of its own.

Attach the part carrying the finite verb: the use is singular, which is why that part reads has been and not have been.

Modifiers then queue in English's default order, field or place before time, and any part opening with a conjunction is pushed to the end.

Key facts

• A part beginning with and joins two complete ideas, so it can never open the sentence.
• The use of animal research is a singular subject, which fixes the verb part as has been.
• Default order after the verb puts field or place before time: in the field of scientific and medical advancements, then throughout the past century.

Common traps

• Reading each option string end to end instead of assembling the sentence first
• Assuming the longest part is the opener
• Missing that it in part (c) needs an antecedent, so part (c) cannot come first
