Alfred Wegener had two flaws with his initial hypothesis. They are as follows:
i) Gravitational forces of the moon and sun, and tidal forces act as the mechanism to move the continents across the globe.
ii) Larger and sturdier continents broke through thinner oceanic crust like boat cutting through a thin layer of sea ice.
<u>Explanation</u>:
Alfred Lothar Wegener was a great meteorologist and German polar researcher. He was commonly known for his <u>“theory of continental drift”.
</u>
In this theory, they proposed an idea that the continents were slowly drifting around the Earth. Many researchers objected his view. But he provided many evidence to support his continental drift hypothesis.
Some of the evidences are: Continental jigsaw puzzle, Fossils match across the seas, Rock types and geologic features and Ancient Climates.

Answer:
The answer is double blind experiment.
Explanation:
In a double blind experiment, neither the researchers nor the participants are aware about which group is receiving the experimental treatment. This is done in order to prevent biases in the participants' judgment (the placebo effect), and prevent the researchers from giving accidental cues.
The greatest advantage of double blind studies is they have greater reliability and validity than other types of studies.
