Which of the following was a negative effect of spanish missions on american indian life?

Many Native Americans converted to Christianity because they thought this was the only way to save themselves from dying from the Europeans' diseases. They also lost their religion. The 'encomienda' system (legalized slavery) also negatorily affected their simple way of life.

Many Native American populations were utterly destroyed by the Europeans' previously unknown diseases long before they ever actually laid eyes on them. Smallpox, chicken pox and the measles were unkown in North America before the Europeans' arrival. 
Thanks to the "Mission System' employed by the Spanish Conquistadores, many Native American religious practices, customs, and uiltimately, languages were lost forever. Many Native Americans were virtually enslaved. Others were outright tricked and killed by the "civilized" intruders.

The price of oil and inflation are connected in a cause and effect relationship, that is, when the price of oil increases, inflation also increases in an economy. this is because, oil is a major input in the economy, that is, it is used for critical purposes such as fueling of vehicles for transportation, for running of industrial generators and machines, for heating homes, etc.for instance, if the price of oil increases in an economy, it will increase the cost of production for those using the oil in their production processes and they will automatically increase the cost of their products in order to offset the extra costs. this leads to general increase in the prices of products in the market and result in inflation.
