3. Most people in Mexico and Central America choose to emigrate in order to
move somewhere warmer.
trade their goods.
find better jobs.
escape religious persecution

The right choice is:

Find better jobs.

Explanation:

Millions of Mexicans and Central Americans decide to go to the United States for two reasons mainly. The first reason is to look  for economic opportunities they don´t  have at home; they want  jobs that are better paid  and to escape poverty.

The second reason is equally important. Many people flee their countries because their personal safety is threatened by criminals gangs known as "maras" , from the threats of drug traffickers; for them, to stay home may mean death. This is particularly true in Guatemala, Honduras and El Salvador, though many Nicaraguans now flee their country to escape repression by the dictatorship of Daniel Ortega, an old leftist comandante who opposed the USA in the 1980s , but he came back to power in 2007.

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 !

what if dreaming is our natural state, and we only wake to collect information for our dreams.

if we were to fully devote our bodies, minds, and consciousness to dreaming, how far would it go? we could essentially reach a new plain of existence were we here in these bodies are sleeping, but an entire universe of endless possibilities, happening right in our head.

that could be the way we reach some of these scientific feats that we all seem to want. we could connect to many other things. that could be the way we connect to extra-terrestrial, and even spirits of the dead.

dreaming is something that humans take for ranted, when really, it could be the key to the universe.
