In each of the questions below, a grammatically coherent sentence is split into four distinct fragments marked as (A), (B), (C), and (D). You are required to sequence these fragments in the correct order to form a logical and grammatically sound sentence. If the sentence is already in the correct sequence, select (E), 'No rearrangement required', as your choice.

basic shelter was (A) / required, like Sweden and Norway (B) / Dry leaves were the primary material gathered (C) / in areas where just (D)

The correct option is CDAB.

To sequence the given sentence fragments into a grammatically coherent and logical sentence, let us analyze each fragment and its logical connections:

Fragment (C): "Dry leaves were the primary material gathered"
This fragment provides the main subject ("Dry leaves") and predicate ("were the primary material gathered"), making it a natural and strong starting point for the sentence.

Fragment (D): "in areas where just"
This fragment naturally follows fragment (C) to indicate the location/context where these dry leaves were gathered ("gathered in areas where just...").

Fragment (A): "basic shelter was"
This completes the clause started in fragment (D): "in areas where just basic shelter was...".

Fragment (B): "required, like Sweden and Norway"
This completes the passive structure "was required" from fragment (A) and provides examples ("like Sweden and Norway").

Combining these fragments in the order (C) → (D) → (A) → (B) gives the complete, grammatically sound sentence:
"Dry leaves were the primary material gathered in areas where just basic shelter was required, like Sweden and Norway."

Therefore, the correct sequence is CDAB.
