Which options represent attempts on the part of the Mexican government to assert control over the Texas Territory?

_(Select all that apply.)_

enforced Spanish as the national language
ended further American immigration
forced American settlers to take a loyalty oath
prohibited slavery
built military posts

B, D, E?

Well, depending on how many points this is worth, you missed two big ones!!

There should only be three correct, so I'm not sure. Those seemed like the best answers.

Do B, D, and E seem correct, though?

I think one of your choices is correct. Please read the following and decide how you'll change your answer:

This may help, too.

Yes, your selected options B (ended further American immigration), D (prohibited slavery), and E (built military posts) correctly represent attempts on the part of the Mexican government to assert control over the Texas Territory.
