In each of the following questions, a sentence has been given with two blanks. For each question, five options are given, each containing two words. You have to choose the most suitable option that fits both the blanks grammatically and contextually.

In summer, the region is bathed in an _____________ of sunlight, with a "midnight sun" that ___________ sets.

The correct option is abundance, never.

Let us analyze the context of the given sentence step-by-step to choose the most suitable words for both blanks:

Analyzing the First Blank:
The sentence mentions a "midnight sun," which refers to a natural phenomenon occurring in polar regions during summer where the sun remains visible even at local midnight. This indicates a very high amount or surplus of sunlight.
- "abundance" means a very large quantity of something, which perfectly matches the phrase "bathed in an abundance of sunlight".
- "absence", "violence", "silence", and "vengeance" do not fit contextually with sunlight in this scenario.

Analyzing the Second Blank:
The second part of the sentence refers to the "midnight sun that ___________ sets." Since the midnight sun stays in the sky continuously during polar summer, it rarely or never sets.
- "never" appropriately completes the thought: a sun that never sets during this period.
- Options like "there", "now", "below", or "soon" do not accurately convey the phenomenon of the midnight sun.

Thus, placing abundance in the first blank and never in the second blank makes the sentence grammatically correct and contextually meaningful:

"In summer, the region is bathed in an abundance of sunlight, with a \"midnight sun\" that never sets."
