| Option | Meaning and use | Example |
|---|---|---|
| (1) must | "Must" expresses obligation or a firm conclusion from evidence ("The ground is wet; it must have rained"). Clouds alone do not make rain certain. | You must wear a helmet on a scooter. |
| (2) should | "Should" gives advice or duty, or what is expected because things are going as planned ("The parcel should reach you tomorrow"). The sentence only guesses at a possibility from the clouds, which is the job of "might". | You should drink more water in summer. |
| (3) can | "Can" expresses ability or what is possible in general ("It can rain heavily in July"). It is not used for a guess about one particular occasion. | She can swim very well. |
| (4) might (answer) | May and might say that something is possible but not certain. | Take an umbrella; it might rain in the evening. |
