A question about liquid pressere

[torukojin]

1. please help me with the following two questions and explain it to me like I am a 15 years old dummy, thanks in advance

The question "Which water jet can be expected at high under pressure?" does not appear to have been written by a native English speaker. It does not make sense. Are we to assume that the water is under high pressure? Or that the ambient air is under high pressure? Is "under pressure" supposed to mean "underpressure" which would likely be a lower-than-ambient pressure.

The question about normal pressure is even less sensible. How are we expected to know what is normal without context?
