Answer:
Jason is experiencing simultaneous bilingualism.
Explanation:
Bilingualism refers to the ability to speak 2 languages. Simultaneous bilingualism refers to an individual acquiring the ability to speak 2 languages because he/she has learnt them simultaneously, which means at the same time.
In this case, Jason's parents speak English at home and when he stays at the day care the people speak Spanish. This means that Jason is learning both languages around the same time and will probably be able to speak both languages.
