The first time she had bubble tea, Maria thought it was weird and gross, but all of her friends loved the strange tapioca in the bottom of their drinks, so Maria decided to give it another try. What shaped her attitude toward bubble tea?

The reasons that shaped her attitude toward bubble tea are:

- Social pressure and need for acceptance.

Explanation:

The Social Pressure acts when a person, in spite to having different pleasures that the other members of a group, is directed to adopt that pleasure simply by to fit in the group (need for acceptance), in María's case, though she thinks the bubble tea seemed weird and gross, how her friends liked it, she was "forced" to drink it how if she loved it too.
