In the question below, a grammatically correct and coherent sentence is split into four fragments labeled (A), (B), (C), and (D). Reorder these fragments to construct a contextually and grammatically correct sentence. If the current sequence is correct and no change is necessary, choose (E) as your answer, indicating 'No rearrangement required'.

in teaching to deliver (A) / to stay updated on modern pedagogy (B) / all educators in schools need (C) / impactful lessons to students (D)

The correct option is CBAD.

To construct a grammatically correct and contextually coherent sentence, let's analyze the given fragments step-by-step:

1. Identify the subject and main verb (Independent Clause):
Fragment (C) "all educators in schools need" introduces the main subject ("all educators in schools") and the transitive verb ("need"). This serves as the logical starting point for the sentence.

2. Determine what is needed (First Infinitive Purpose):
Following the verb "need", fragment (B) "to stay updated on modern pedagogy" provides the first infinitive phrase ("to stay updated...") explaining what educators need to do.

3. Connect the second infinitive phrase:
Fragment (A) "in teaching to deliver" logically links the context of teaching with the goal of delivering something. When placed after (B), it creates the smooth flow: "...to stay updated on modern pedagogy in teaching to deliver..."

4. Complete the object of the infinitive:
Fragment (D) "impactful lessons to students" serves as the direct object for the verb "deliver" in fragment (A). Delivering what? "impactful lessons to students".

Combining the fragments in the order (C) → (B) → (A) → (D) forms the complete and coherent sentence:

"All educators in schools need to stay updated on modern pedagogy in teaching to deliver impactful lessons to students."
