Answer:
Step-by-step explanation:
First of all, the grammar in the first sentence is wrong. To put "jamais", you need to put "ne" before. So it should be like this: Moi, je ne __ jamais au basket.
Ok. Now the answer: Since "Je" is the 1st personne in singular form, and it is an "ER" verb (jouER), you will need a terminaison of "E".
So neither of the choices are good. It should be like this:
Moi, je ne joue jamais au basket.
For the second sentence, we use "on". It is the 3e personne in singular form, and it is an irregular verb (Aller; to go). So we won't rely on the "normal conjugation". So you'll need to memorize this verb by heart.
Ok. The conjugation for the verb "Aller" in 3e personne of singular form is "va".
So the choice should be like this:
Pour faire du shopping, on va au centre commercial.
Remember that "Vas" is the 2nd personne singular form of Aller (To go); and "Est" is the 3rd personne singular form of Etre (To be).
