In 1979, the United States began developing trade agreements with China. Ten years later, the United States decided not to break off its trade relationship with China, despite the communist government’s crackdown on political dissent. How might trade agreements lead to political change?

Changes the demands and forces reform

Explanation:

Trade agreements will open the opportunity for governments to be come allies with other countries. This type of new relationship will encourage international recognition. This will lead to the establishment of new embassies and  recognition of each other as countries.  

Moreover, trade agreements will put a spotlight on specific countries and bring to the forefront their policies and procedures and political misgivings. Since they will be viewed now, by the entire world, and more importantly, the country they are in trade with, the political reforms to offer better optics on an international scale will begin to evolve.

Trade agreements will encourage countries to be politically favorable towards the countries they are in exchange with and in some cases this may modernize their political scheme.

the doctrine of nullification recommended that states living inside the union have the one-sided, inalienable ideal to void any law made by the national government that could be esteemed illegal.

the united states was shaped based on a general agreement among its individual states. hence, it is inferred that under the hypothesis of invalidation, since the states are the establishment of the union, they have the ability to referee and disprove unlawful laws.

biological/genetic factors means they were born or predisposed to have something. nothing can really change it, and you can't really do much to "fix" it. it isn't something learned

these are the biological factors:

adrian is relatively tall and he is on the basketball team

(adrian can't ever stop being tall or force himself to be tall. likely one or both of his parents are tall as well and they passed on the tall gene. he probably does basketball because he is tall)

the rest are environmental/cultural factors. these are things that are taught to us. for example, cynthia wasn't born saving pocket money, her family most likely taught her this (environmental factor)

hope this !
