Mark the consequence if it is intentional. a. spanish conquistadors bring their horses with them across the atlantic. some horses escape or swim to shore after a ship sinks. the plains indians become expert horsemen and buffalo hunters. b. rats are aboard european ships coming to the americas. the rats spread disease and hunt unknown numbers of smaller animals to extinction. c. columbus brought pigs to the americas on his second voyage. the pigs provided a valuable source of food for a growing population.

A. Spanish conquistadors bring their horses with them across the Atlantic. Some horses escape or swim to shore after a ship sinks. The Plains Indians become expert horsemen and buffalo hunters.

This was certainly not intentional since hardly the conquistadors would want their enemies to be stronger.

B. B. Rats are aboard European ships coming to the Americas. The rats spread disease and hunt unknown numbers of smaller animals to extinction.

This is hardly intentional. Rats were almost unavoidable back then and the Europeans just did not care much about them. They weren't thinking about how the rats would cause trouble in the Americas. They were "just rats".

So the only intentional one is:

C. Columbus brought pigs to the Americas on his second voyage. The pigs provided a valuable source of food for a growing population.

Columbus brought pigs for them to serve as food eventually and so they did.

Option:  C. Columbus brought pigs to the Americas on his second voyage. The pigs provided a valuable source of food for a growing population.

Explanation:

Columbus brought pigs in the New World on his second voyages during Columbia exchange for the Spanish settlers who were increasing in numbers. Pigs became a source of food for the settlers apart from fish and crops. Settlers in the New world used the pigs not only for consumption as fresh meat but use the meat for making salt pork to preserve it for longer.

overtime, the civil rights movement changed in a way that not only it benefited african-americans, but benefited other ethnicity's such as latinos, asians, or women too! that's why the results of the movement be called mixed.

the civil rights movement brought about tremendous changes. no longer were blacks denied the right to vote, to eat, shop, and swim where they , and more importantly, to attend integrated schools. despite its many accomplishments, however, the civil rights movement had its shortcomings. for example, many people, both young and old, lost their lives, homes, jobs, and families. still other individuals were so damaged by psychological trauma that they ceased being productive members of the community. the movement left intact the economic inequities that had contributed to the maintenance of segregation. and finally, racism remained alive and well long after the movement's end. like most movements of its kind, the civil rights movement left behind a mixed legacy of triumph and tragedy.
