she is the one responsible of having to deal with certain issues in support of the

Even though all of the above reasons may be critical pull factors, we could safely lean towards option B, <em>higher wages</em>, as the most indicative answer. Mexicans did not necessarily get better jobs than they had back in their native country, where they may even have been skilled and educated professionals; in fact, wages may have been significantly higher in comparison to their earnings at home, allowing them for having a better quality of life and affording medical care, which tends to be expensive in the USA. Education is not necessarily free -especially at its highest levels, which would help migrants and their offspring to still further improve their quality of life- but then again, higher wages could open the possibility of accessing some private higher education.
Climate can affect a lot about you: Such as If you live in a humid (Hot and sticky) area would you wear a fur coat & live in an igloo? (I should hope not) Or If you lived in the North (Where it snows A LOT!) would you wear shorts & a sleeveless t-shirt or live in a a house without insulation?
-Hope this helps!
