Answer: d. Confounding
Explanation:
In the context of a scientific study such as this one, a confounding factor is one that has influence on both the exposure and event variable(s), which may lead to over- or underestimation of the direct relationship between them (if any).
For instance: In this example, researchers may have had reason to believe that male gender is associated with both higher risk of obesity (the exposure variable) and adult-onset asthma (the event variable). If gender is not taken into account, one may claim that the finding of an association between obesity and asthma is simply an artifact due to the high proportion of male patients (likely to present with both). <em>Controlling</em> for that variable (such as by matching, as in this example) allows researchers to test for this hypothesis.
Answer: Broca's area
Explanation:
Broca's area is primarily responsible for producing speech. It controls motor functions involved with speech production. It is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain.
People who have damage to this area of the brain can understand words but struggle to put them together in speech. Tony clearly has no problem processing what is being said but because of the damage he can't put his thoughts to words.
Answer:
forensic linguist
Explanation:
From the available options provided the only individual position that does this would be a forensic linguist. The responsibilities of this position include analyzing language on text or recorded documents. They do this in order to understand and uncover different details within the document that may help law enforcement solve a crime. This also involves studying abbreviations used in text messages to identify the author, what the abbreviation means, in what context it is being used, hidden meanings, etc. All of which can be highly valuable in a criminal case.
