Pomoc w zadaniu dom. - czas przyszły

Mam zadanie z użciem odp. czasu. Czy w przykładach:
a) Have you bought flowers for Edwina yet?
Not yet, but I _________ (buy) them in the afternoon. Look, the're on my shopping list. użyję Present Continous?
b)It's very busy restaurant. Have you booked a table?
No, but I think we ____________(get) a table easily. It's still earlt in the evening. uzyję konstr. be going to?

Wg mnie w zdaniu pierwszym 'to be going to', w zdaniu drugim 'will'

Have you bought flowers for Edwina yet?
Not yet, but I AM BUYING / AM GOING TO BUY them in the afternoon. Look, they're on my shopping list.

It's very busy restaurant. Have you booked a table?
No, but I think we WILL GET / ARE GOING TO GET a table easily. It's still early in the evening.

Co do 2. zdania, jeżeli jest to do jakichś testów, zadanie domowe itp., to napisz WILL, jako że formy BE GOING TO stosuje się kolokwialnie w takim kontekscie.
