Question

Can someone check my work?
1. Choose the correct possessive adjective to complete the sentence:

(your formal) boulangerie est grande.
leur
vos
votre <-- My answer.
notre

2. Fill in the blank with the correct singular possessive adjective: (your)
C'est __(ta)__ tante au téléphone.

Answer 1

Answer 2

Your answer is correct.
Leur is their
vos is your (but with plural objects, such as your parents, your books, etc.)
votre is your (with singular object)
notre is our

For the second question, I'm not sure if "singular" refers to ta tante (as opposed to votre), or votre tante (singular object tante) as opposed to plural object vos tantes.
In any case, your answer is grammatically correct.
