Directions (21-24):In each of the questions given below, four words have been highlighted. These four words may or may not have been placed in their correct positions. The sentence is then followed by options with the correct combination of words that should replace each other in order to make the sentence grammatically and contextually correct. Find the correct combination of the words that should replace each other. If the sentence is correct as it is, then select option (e) as your choice.

The BRICS provides an appropriate shape (A) model suitable for the 21st century where a dominated (B) group of states narrow (C) by one power will not governance (D) the agenda.

The correct answer is A-D & B-C.

To determine the correct placement of the highlighted words, let us analyze the sentence grammatically and contextually:

Original Sentence:
"The BRICS provides an appropriate shape (A) model suitable for the 21st century where a dominated (B) group of states narrow (C) by one power will not governance (D) the agenda."

Analysis of Word Swaps:

1. Replacing A with D (shape ↔ governance):
In position (D), after the modal auxiliary verb "will not", we require a base form verb (V1). "Governance" is a noun, whereas "shape" can function as a verb meaning to guide or determine. Thus, "shape" correctly fits in position (D): "...will not shape the agenda."
Conversely, in position (A), before the noun "model", we need a noun to form a compound noun or modification. "Governance model" is a standard contextual phrase describing a framework of governing. Thus, "governance" fits in position (A): "...appropriate governance model..."

2. Replacing B with C (dominated ↔ narrow):
In position (B), before the noun phrase "group of states", an adjective is required. "Narrow" acts as an adjective describing the restricted or exclusive nature of the group: "...a narrow group of states...".
In position (C), modifying the prepositional phrase "by one power", a past participle verb/adjective is required. "Dominated" fits grammatically and logically: "...dominated by one power...".

Corrected Sentence:
"The BRICS provides an appropriate governance model suitable for the 21st century where a narrow group of states dominated by one power will not shape the agenda."

Therefore, the word pairs that must be swapped are A-D and B-C.
