Peterson and peterson studied how well participants can remember groups of three letters (like brt, qsd) after various delays. they found that participants remembered an average of 80 percent of the groups after 3 seconds but only 10 percent after 18 seconds. they hypothesized that this decrease in performance was due to but later research showed that it was actually due to

decay, interference

Explanation:

Peterson and Peterson studied how well participants can remember groups of three letters (like BRT, QSD) after various delays. They found that participants remembered an average of 80 percent of the groups after 3 seconds but only 10 percent after 18 seconds. They hypothesized that this decrease in performance was due to decay, but later research showed that it was actually due to interference.

the above statement/question is (true);

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
