How do scientist in present day study the triassic era

I would say we have better technology, so they can take part of the DNA and see when they were around. How long it's been since a dinosaur in the Triassic Era walked the earth.

Explanation:

Paleontologists, they study fossils which help them get a better understanding of what existed and happened during the triassic era.

the correct answer option is: weapons.

explanation:

tensions rose as the two opposing superpowers competed for 'weapons'.

referring to the cold war (1945-1991), the two superpowers, usa and ussr, experienced a phase of struggle and conflict with each other. these two superpowers considered each other as a threat to their survival and thus opted for policies to strengthen their positions.

the two superpowers never went to war with each other directly but competed for weapons to preserve their positions.

c. is the answer : ) (you may punch me if im wrong lol)
