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.

Explanation
Soap’s dual polar and nonpolar nature helps bond oil and water. Soap is an emulsifier, which means that it has both polar and nonpolar regions. The polar regions of soap molecules are attracted to water, while the nonpolar regions are attracted to oil and grease. This allows soap to bond with both water and oil, helping to remove dirt and grime from surfaces.
B. Soap’s acidity does not cause grime to precipitate into the water.
C. Soap does not have enzymatic action that helps to dissolve grime into small particles.
D. Soap’s texture does not physically scour grime off surfaces.

B. The brain and spinal cord are not located in the thoracic cavity and are therefore not at greatest risk from blunt trauma to this area.
