Fill in the blank with a suitable determiner from below.

I cannot read in this light because there are too ________ insects.

many

In this sentence, the determiner "many" is used to indicate a large number of insects, which is affecting the ability to read in the given light. The presence of a significant number of insects is being emphasized as the reason for the difficulty in reading.. Therefore, the best option to fill the blank is: many.

Here's why:

• A few suggests a small number of insects, which wouldn't necessarily be enough to disrupt reading.
• A little is typically used with uncountable nouns or to express a small quantity. It doesn't fit with "insects," which are countable.
• Many indicates a significant number of insects, enough to be distracting and make reading difficult. This aligns with the intended meaning of the sentence.
• Most implies that almost all insects are present, which is an exaggeration and not necessary for the scenario.
