Experiments cannot validate hypotheses, only falsify them. The statement above can be restated in which of the following ways?
Until disproved, an explanation for an observation is valid.
Certain concepts cannot be subjected to direct experimentation.
A hypothesis that has not been falsified remains provisional.
Proving a hypothesis exempts it from further testing.
The Correct Answer is C
The statement "Experiments cannot validate hypotheses, only falsify them" can be restated as "A hypothesis that has not been falsified remains provisional." This means that a hypothesis is considered valid until it is disproved by experimental evidence. However, even if a hypothesis has not been falsified, it is still considered provisional and subject to further testing and scrutiny.
A. "Until disproved, an explanation for an observation is valid" is similar to the correct answer but does not capture the provisional nature of a hypothesis.
B. "Certain concepts cannot be subjected to direct experimentation" is not a restatement of the original statement.
D. "Proving a hypothesis exempts it from further testing" is incorrect because no hypothesis can be definitively proven and all hypotheses are subject to further testing and scrutiny.

Correct Answer is B
Explanation
The doctor refuses to prescribe antibiotics to the patient because the illness is caused by a virus. The common cold is a viral infection of the upper respiratory tract ⁴. Antibiotics are not effective against viral infections and are only used to treat bacterial infections.
The other options are not correct because they do not accurately describe the cause of the common cold and sore throat. Fungus, protist, and bacteria are not the pathogens responsible for causing the common cold .
