In the given question, a statement divided into different segments is given. Rearrange all the segments to form a coherent statement. If no rearrangement is required select “No rearrangement required” as correct answer.

A: of prolonged droughts and extreme heat

B: climate change is intensifying the frequency

C: across various parts of the globe

D: impacting agriculture and water supply

E: causing significant ecological imbalances

To find the correct order of the given segments to form a coherent statement, let us analyze the meaning and grammatical connection of each segment:

A: of prolonged droughts and extreme heat
B: climate change is intensifying the frequency
C: across various parts of the globe
D: impacting agriculture and water supply
E: causing significant ecological imbalances

Let's look for grammatical links between the segments:

1. Segment B ("climate change is intensifying the frequency") ends with the noun "frequency". Grammatically, "frequency" is typically followed by the preposition "of" to describe what frequency is referred to. Segment A begins with "of prolonged droughts and extreme heat". This forms a logical and grammatical link: B ⇒ A ("climate change is intensifying the frequency of prolonged droughts and extreme heat").
2. Following the description of the droughts and heat in segment A, we can state where this is happening. Segment C ("across various parts of the globe") logically fits next to modify the location of these climatic events. This gives us the sequence B ⇒ A ⇒ C.
3. Next, we need to describe the consequences of these intensified events. Segments D ("impacting agriculture and water supply") and E ("causing significant ecological imbalances") both begin with present participles ("impacting", "causing") acting as modifiers. Connecting them in the order D ⇒ E gives a smooth flow of consequences, linked as B ⇒ A ⇒ C ⇒ D ⇒ E.

Let us read the complete rearranged sentence in the order BACDE:
"Climate change is intensifying the frequency of prolonged droughts and extreme heat across various parts of the globe, impacting agriculture and water supply, causing significant ecological imbalances."

This forms a grammatically correct, coherent, and logical statement. Therefore, the correct arrangement is BACDE.
