The author who quotes the video game researcher is using statistical argument.
<h3>What is statistical argument?</h3>
Statistical argument is an argument based on facts and figures from a research. This kind of argument requires the researcher to get values in order to make judgement.
Children who earn poor grades in school do well in playing video games. This is because, the researcher has found out how low they perform in class in terms of their test score and has used this as a measure to determine how poor they play video games.

Answer: A- unlucky or unfortunate; pitiable
Explanation: The words around it help me figure out the meaning!
The specific heat of the given sample of metal is 14.32 J/kg.K.
<h3>What is the Specific heat of a sample?</h3>
The specific heat of a sample is the amount of heat needed or required to raise the temperature of that sample by 1K. It is given by the formula:
Q = mCΔT
where;
- Q = Heat transferred
- m = Mass of the substance
- C = Specific heat
- ΔT= Change in temperature.
Recall that:
weight of a substance = mass × gravity
- mass = 28.4 N/ 9.8 m/s²
- mass = 3 N/m/s² = 3 kg
From the equation:
Q = mCΔT
C = 14.32 J/kg.K
