Explanation:

Sarula recently completed a compatibility "quiz" from one of her favorite magazines, and although she and her boyfriend have been dating for nearly two years, the "quiz" results suggested they are not compatible. luckily, riley, one of sarula's friends, is a student of psychology and suggested that the "quiz" may not be valid. what is her friend suggesting?

Sarula's friend is suggesting that the quiz may not actually measure compatibility

Validity refers to the extent to which a test or measure actually measures what it claims or sets out to measure. For a test to give an accurate result, it is important for the test to be valid. In this instance, the quiz  Sarula took from the magazine may not be valid, since it probably is not based on legitimate scientific research. The quiz might have assessed things that have nothing to do with relationship compatibility.

b. the opinions of chiefs of higher status are worth more than those of chiefs below them
c. the high chief has final say in all matters relating to the village

The correct answer is B; The opinions of chiefs of higher status are worth more than those of chiefs below them.

Further Explanation:

In the Samoan culture, as a person ages the status they have in the village raises significantly. The older a person is the less responsibility they have. When the council meets, they listen to the opinions of the higher chiefs since they are older and wiser.

The council also plans things such as the agriculture life and what will be planted and when. They do this to cut down on stealing. Samoan families usually own the land that their village sits on.
