In science we like to operate between 2 kinds of analysis: 1) The qualitative analysis. 2) The quantitative analysis. The qualitative analysis, is usually a binary analysis on a variable where we can say "true" or "false". The quantitative analysis, is the analysis using numeric value to a test, compared to a reference used for the experiment. Examples of using both analysis could be on temperature and could be outlined as follow: "We consider a chemical reaction and are interest in the temperature before and after the reaction is carried out" Question using qualitative analysis: "Will the temperature change when the chemical reaction is done?" Answer: "Yes" or "no" Question using quantitative analysis: "How MUCH will the temperature increase after the chemical reaction?" Answer: a numerical value compared to a reference. Based on that, answer your question.

In addtion to that I suggest you post each question individually, we know from experience there is a higher chance of getting questions answered. Along with that, we may not just answer tests by writing a letter/number to each question. In that case it is best you try your self and some may take the time to check if they are correct.
