Question

Both Gregor Mendel and Alfred Wegener proposed ideas that were not accepted completely by the scientific community during their lifetimes. What did their ideas have in common?

They were presented by amateur scientists who were not accepted by the scientific community.
They explained aspects of genetics that required Watson and Crick's data to be understandable.
They needed mathematics to prove their data, and that field was not developed at the time.
They required supporting evidence which could not be provided with the existing technology.

Answer 1

They required supporting evidence which could not be provided with the existing technology!

Answer 2

Correct answer: D). They required supporting evidence which could not be provided with the existing technology.

Both the scientist Gregor Mendel and Alfred Wegener proposed their idea but the scientific community do not believe to their ideas they talk about genetics and DNA and at that time the technology was not developed to study such information. So, they prove their ideas and theories but are not able to explain them to the people.

Hence, the correct answer would be option D.
