I am writing a scientific paper, and would like my diction to be as precise as possible. Regarding the subjunctive mood, I know the following is correct:
"It is important that she be at home by 9 p.m.".
"The probability that temperature exceeds its historical maximum is large."
sounds to me better than
"The probability that temperature exceed its historical maximum is large."
Which one is correct? Is it a matter of taste?
