Another common structure, and by now the pattern is familiar: que is doing the work of introducing the mood tense.
es + adjective + que + mood tense
Es terrible que comas esto · Es posible que vayamos más tarde · No es necesario que responda · Es importante que lo encontremos pronto · Qué fuerte que esté aquí
You can also use no hace falta que responda, that common expression meaning it is not necessary.
The contrast that isolates what que is doing. Swap it for si and the mood tense disappears.
English reaches a similar feeling using those words in a non-literal way. How incredible that he should come does not mean should in the sense of debería: it is doing mood-tense work.
Está bien que preguntes carries the sense of it's okay that you might ask, so ask as much as you like.
Fuerte means strong, but colloquially it is used the way English says that's full-on or that's hardcore.
Add que and continue into the mood tense: qué fuerte que esté aquí, giving two ques in a row.
Bien is literally well, and being well is a state, so it goes with estar.
Está bien que preguntes, pero no es necesario que responda
Worth repeating because the instinct is so strong. Your mind goes to choosing between ser and estar first.
Debería haber algo para comer (there should be something to eat)
Note para comer: the to here means in order to.
