Answer 1

QUESTION 1

The correct answer is Supported by a large amount of data. Remember that a scientific theory is established using a group of accumulated data that together are able to describe a phenomena. In this case, the theory of gravity has been highly studied by a diverse of researcher that together stablished how the gravity works.

QUESTION 2

Do sounds from the basement come from ghosts? Is not a hypothesis. In most of the cases, a hypothesis is redacted as a conditional, “if I do something, I expect this result”. What we are observing here is a question or an observation. This question can be answered using an hypothesis, for example “If the sounds come from ghosts, we will observe them at the basement”
