4, el sándwich. It means the sandwich, and 'sandwitch' is an english word.
Quien hace caso a las adulaciones se cree el grande , que no hay alguien mejor y no busca mejorar
(Assuming the myth is referring to the United States)
The myth comes from people who don't like immigrants and who don't want immigrants to come to their country.
A person who might be xenophobic or someone who already lives in the country that the immigrants are coming from. For example an American who doesn't want someone from Latin America coming over. They may benefit from this myth to victimize themselves that the country is being "overrun by illegals".
This myth is untrue because there are many legal immigrants that arrive here legally.
Remember that the way this verb conjuncts is as follows:
yo - Pienso
tu - Piensas
ella,el,usted - Piensa
nosotros(as) - Pensamos
vosotros(as) - Pensais
ellos,ellas,ustedes - piensan
Hope this helps :)
