Which of the following is an example of quantitative data?
a. observing the color change in a chemical change
b. classifying the sweetness of artificial sweeteners
c. measuring the temperature change in a chemical reaction

Measuring the temperature change in a chemical reaction

Explanation:

Both colors and sweetness are subjective. For example, someone could be colorblind, or someone could have a very high sweetness tolerance so something that is barely sweet to them tastes incredibly sweet to another person. Temperature, however, cannot be disputed as there is an exact way to measure that.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
