The correct answer is called Correlating
Explanation
Correlating or correlating rock layers is an instrument to determine the age of rocks, it means fossils are used to determine the age of rock layers, for this process it is necessary the fossil had lived a short time so they are sure it appears in only one layer and belongs just to one specific age. Later these fossils are matched to different rocks or layers and thus, different areas with the same fossils can be studied and compared to determine the age of each of the layers above or under the fossil. Also, the word correlation refers to two or more objects, people or other being related to each other as in the case of fossils and rock whose age is related and thus can be correlated or matched up.
Immigrants bring ideas that are dangerous to the American way of life.
Immigrants are unable to assimilate successfully into mainstream society.
Immigrants consume scarce natural resources needed for the native-born population.
The correct answer is:
Immigrants contribute to unemployment among native-born workers.
This was and even nowadays is a common case, because normally people who immigrate are from the third world countries (in the majority of cases) and they are ready to go to any work, even if it is physically hard. In such way, they leave very little choice to the native-born workers or even take options available for them.
Economic factors influenced political developments in the annexation of Hawaii because American planters in Hawaii pushed for annexation so that the sugar trade could be opened to markets in the U.S. Many American sailors and settlers were drawn to Hawaii's tropical islands. Some of the descendants started sugar plantations and traded with the U.S. The Queen was alarmed by the settlers power and in response they seized power asking the U.S. to annex Hawaii.
