Directions: In the sentence given below, four words are highlighted in bold. These four words may or may not be in their correct positions. The sentence is followed by options representing the correct pair(s) of words that should be interchanged to make the sentence grammatically and contextually correct. Choose the correct combination of words. If the sentence is already correct, select 'No correction required'.

Resource depletion is a threat (1) and the pace of consumption (2) has accelerated lately, particularly after industrialization, and it is not logical to blame (3) the depletion on progress alone (4).

The correct answer is No correction required.

Step-by-step Explanation:
To evaluate whether any words need to be interchanged, let us analyze the context, meaning, and grammatical function of each highlighted word in its current position:

1. threat (1): In the clause "Resource depletion is a threat", the word "threat" functions as a noun indicating danger or harm. Contextually, resource depletion posing a hazard makes complete sense. Grammatically, it correctly follows the indefinite article "a".

2. consumption (2): In the clause "the pace of consumption has accelerated lately", "consumption" refers to the rate at which resources are used up. This logically links to the expansion of industrialization and the depletion of resources.

3. blame (3): In the phrase "it is not logical to blame the depletion on progress", the verb "blame" forms the infinitive "to blame" and correctly follows the standard prepositiional structure "blame [something] on [something]".

4. alone (4): In the phrase "on progress alone", "alone" functions as a modifier meaning "solely" or "exclusively", conveying that progress is not the single cause of resource depletion.

Because all four words are contextually meaningful and grammatically sound in their original positions, no word swap is needed. Therefore, the sentence is already correct.
