Atautology is always false. always true. sometimes true. sometimes false.

The correct answer is B. Always true

Explanation:

In rhetoric, the term "tautology" refers to statements or formula based on logic that usually states one idea and then uses different words to refer to the same idea without inconsistencies in the process of logic or language, because of this it is considered tautologies are always true even under any possible interpretation, indeed tautologies are considered as logically valid formulas. For example, the statement "A flower is either red or the flower is not red" is a tautology as the premise "A flower is either" is the same that the conclusion "or the flower is not red" as if a flower is not red it is of any other color, which makes this idea consistent and logic. Therefore it can be concluded a tautology is always 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.
