Step-by-step explanation:
At first it might be difficult to conjugate properly, but remember you have to sort it by gender and number. In this exercise you were asked to complete verbs with terminations -AR, -ER & -IR.
All of them are conjugated differently so I suggest you practice by writing sentences or by speaking.
Hope you get it soon, sorry if I can't help you too much ;)
