Answer 2

Only sentences 2 and 3 are grammatically correct.

Explanation:

• The sentence means that a certain criteria was established on the basis of certain responses that were gathered from the inspection of a cross-sectional survey. This sentence is not grammatically correct and the preposition to must be replaced with the preposition of.
• The second sentence means that the students of a certain Chinese university were taken as interns for a job which included being a part of a discussion and actively participate in the panel for checking the quality of tofu which is scientifically modified.
• The third sentence is correct.
• The fourth sentence is grammatically wrong since we use between when we talk of relations between two objects and among when we have to strike differences when there is a presence of many objects.

Hence, Only sentences 2 and 3 are grammatically correct.
