This question is incomplete, here´s the complete question.
Wei-Chin designed a self-report inventory to measure how intimate partners express affection and hostility toward each other. The inventory is a list of positive behaviors (e.g., back rubs, holding hands) and negative behaviors (e.g., slamming doors, raising voices). After having a wide range of couples complete the inventory, Wei-Chin finds that happy couples endorse all the affection items and unhappy couples endorse all the hostile items. Which of the following problems prevents him from concluding that happy couples exchange more affectionate behaviors than unhappy couples?
1. sentiment override
2. item-overlap problem
3. correlation does not imply causation
4. social desirability effect
Answer: 3. Correlation does not imply causation.
Explanation:
Correlation is a statistical technique that evaluates how much two variables are linearly related, meaning they change together. However, two variables being correlated does not necessarily mean that one causes the other. Causation states that any change in a variable will cause a change in another variable.
The fact that happy couples endorsed all the positive behaviors, and unhappy couples the negative ones, shows that there´s a correlation, but it doesn't necessarily mean that unhappiness causes couples to exchange more negative behaviors, or vice-versa.
In 1923, the National Flag Conference called for the words "my Flag" to be changed to "the Flag of the United States," so that new immigrants would not confuse loyalties between their birth countries and the US.
The correct answer is C. Eventually
Explanation:
An appropriate transition should always show the relationship between two sentences or two grammatical elements. In the case of the sentence "The Tennessee Valley Authority erected 20 dams, ________ providing much-needed jobs for up to 40,000 workers" it is suggested the jobs given to 40,000 workers were the result or consequence to the construction of 20 dams.
According to this, it is necessary to include a consequence transition such as therefore, thus or eventually. This means in this case the best option is "eventually" because this is the only transition that shows the consequence relationship between the two sentences; while the transition "because of" is used to show cause, "despite" is used to show contrast and "in addition" is used to add information.
