Which one of the following pairs of technicians could repair all and only the same types of machines as each other?

I’m confused on what this question is asking for

If they’re repairing all and only the same types of machines, wouldn’t that mean they both have to repair all three? The phrasing of this question is confusing me.

Hi @bcross,

I agree, this wording is a bit confusing!

The question stem is asking you to identify which pair of technicians repair the exact same types of machines as each other. The phrase "all and only the same types" means that each technician repairs all the same machines as the other does and that they only repair these machines.

For example, if Urma repairs only radios and televisions, then Xenia would also repair only radios and televisions. The two technicians repair all the same types of machines and they only repair the same types of machines.

Hope this is helpful! Please let us know if you have any further questions.
