The correct answer for: Polls that seek to read the public's mind simply by asking the same question of a large number of people is an example of a . Is: D) Straw vote poll

Explanation:

To understand the answer we need to know the concept. First, straw vote polls are an instrument to gather information from a big number o people. They take the principle of targeting as many random people as they can with their questions. Research instruments don't only target as many people as they can, they actually determine a certain population to gather information about the chosen topic. However, this kind of instrument in the first place doesn't follow any rule to pick the person and in second place they consider absolutes. So if the majority of the people say chocolate bars with chili is good. Even if it is 51% they consider that all the population agrees that chocolate bars with chili are good.

i would say b. research typically uses a variety of sources
