(A) in medicine to provide

(B) to keep abreast of evolving knowledge

(C) all practitioners of medicine need

(D) competent care to patients

In the question below, a grammatically correct and meaningful sentence is given which is divided into four parts namely (A), (B), (C) and (D). Rearrange these four parts to make a contextually and grammatically meaningful sentence. If no such rearrangement is needed, mark 'No rearrangement required' as the answe choice.

To find the correct rearrangement, let us analyze the grammatical connection between the given parts:

1. Identify the subject: Part (C) "all practitioners of medicine need" introduces the subject ("all practitioners of medicine") and the auxiliary verb "need". Therefore, this is the most logical starting point of the sentence.
2. Find the complement for the verb: The verb "need" requires an infinitive to complete its meaning. Part (B) "to keep abreast of evolving knowledge" starts with the infinitive "to keep" and naturally follows (C). This gives us the sequence C-B ("all practitioners of medicine need to keep abreast of evolving knowledge").
3. Connect to the domain and purpose: The phrase "evolving knowledge" is contextually completed by specifying the field in Part (A) "in medicine to provide", which also introduces the purpose infinitive "to provide". This forms the sequence C-B-A.
4. Complete the object of the purpose clause: The action "to provide" in Part (A) requires a direct object. Part (D) "competent care to patients" provides this object and concludes the statement. This yields the sequence C-B-A-D.

By putting these parts together in the order of CBAD, we get the complete, meaningful sentence:
"All practitioners of medicine need to keep abreast of evolving knowledge in medicine to provide competent care to patients."
