Answer 2

Answer:

Long hours and unsociable shifts can take a toll on their health.​

Explanation:

• "Can" is a commonly used modal verb in the English language.
• The verb "can" is often used in sentences where the speaker denotes "ability", "opportunity", "requests", "granting permissions", "expressing a possibility or an impossibility", and so on.
• The verb "can" comes first and foremost in the verb phrase. It is placed just after the subject of the sentence and before another verb.
• It cannot be written with another modal verb in the same sentence, for instance, "can" and "might" cannot be used after one another.
• The negative form of the verb "can" is written as "cannot".
• It is not used with "do", "does", or "doesn't".
• The given sentence, hence, will be written as: Long hours and unsociable shifts can take a toll on their health.​
• Here, a possibility is denoted.
