Answer 1

My printer doesn't work. It might be out of ink.

(Para dar a ideia de um talvez mais incerto, usa-se o  modal verb 'might')

I have no idea what this object is. It should be a computer componet.

(Aqui usamos o should pois neste caso ele serve para demonstrar uma suposição, o mesmo que I think)

It may come to your party tonight.

(Possibilidade incerta. Mas por que o may, e não might? Não sei, mas a prática te impele a saber qual usar)

The construction can't be finished. It only started yesterday!

They're getting married. They must love each other very much.

(likely = provavel/should, very likely = muito provavel(??)/must)
