Consider the following examples:


1. Drinking and driving IS illegal

2. Drinking and driving ARE illegal

3. Stealing and murdering IS illegal

4. Stealing and murdering ARE illegal


According to me, #1 and #4 are correct. The "rule" that I apply is that if the two preceding verbs are combined into a single activity, then the singular form of the joining verb (IS) should be used. If the two preceding verbs are independent actions, then the plural form of the joining verb (ARE) should be used. No one in my office agrees with me, and I cannot find an authoritative guide anywhere online.

Any suggestions?

Ask your co-workers if "Drinking and Driving" is one activity, or two.

It seems to me that drinking and driving are two seperate activities.  Therefore are is correct.

If you mean driving under the spell of liquor, driving drunk is illegal is better.

But if they are used as two separate activities they wouldn't be illegal, unless you were a woman in Saudi Arabia.

Example: Drinking and driving are illegal in Saudi Arabia for women.
