Is it true that as the operating pressure increases during evaporation, the boiling point of the solute rises?

The greater the surface pressure, the higher the boiling point, just like in a pressure cooker.
If it’s a test question, I think this statement needs to be reconsidered. The question mentions the solute; for example, when evaporating a sodium chloride solution, the solutes are chloride ions and sodium ions. It’s necessary to examine whether the boiling point can indeed increase, and whether the term \"boiling point\" is appropriate in this context. But if it’s said casually, I think there should be no problem; the boiling point increases.
Since it is a solute, it is necessary to distinguish which type of solute it is. I think this sentence is not precise.
