Complete the following sentence with a suitable alternative from the options given below:

The sky is cloudy, it __________ rain.

might

The best option to complete the sentence "The sky is cloudy, it __________ rain" is: might

Here's why:

• must: "Must" implies a strong certainty, which isn't appropriate as the cloudiness doesn't guarantee rain.
• should: "Should" suggests obligation or expectation, which doesn't fit the context of a natural phenomenon like rain.
• can: "Can" indicates possibility but can also imply ability, which doesn't directly relate to the weather phenomenon.

"Might" accurately conveys the possibility of rain due to the cloudy sky without making overly strong claims or expectations. It leaves room for uncertainty and reflects the unpredictable nature of weather.
