Explanation:
Limitations of Correlations
Correlation is not and cannot be taken to imply causation. Even if there is a very strong association between two variables we cannot assume that one causes the other. For example suppose we found a positive correlation between watching violence on T.V. and violent behavior in adolescence.
An important limitation of correlational research designs is that they cannot be used to draw conclusions about the causal relationships among the measured variables. Consider, for instance, a researcher who has hypothesized that viewing violent behavior will cause increased aggressive play in children

the original line is stating that heart disease and strokes were the two leading killers 20 years ago, and they still are today so this means that heart issues are a big problem and main cause of death.
Answer:
The correct answer is D.
Explanation:
The normal value range of pH is 7,35-7,45.
If the pH es <u>higher than 7,45</u> we say it is alkalosis and if the pH es <u>lower than 7,35</u> we say it is acidosis. That being said, we can now rule out option B and C.
Then we have to define <u>respiratory acidosis:</u> it is a decrease of pH because of a high value of PaCO2 (in this case as a result of hypoventilation). The normal range of PaCO2 is 35-45 mmHg.
So if we take all this in consideration, the only option with a low pH and a high paCO2 is option D.
