Answer:
The correct answer is 2. The purpose of this poster was to keep morale up at the Home Front.
Explanation:
During World War II, the Allied nations mobilized huge numbers of personnel to militarily defeat the Axis powers. This caused millions of workers in these nations to leave their jobs to go to war. Thus, the production of these nations took on enormous importance, destined almost exclusively to satisfy and supply the demands of the battle front: the group of people who stayed in their countries producing began to be called members of the Home Front, giving them a fundamental importance as suppliers of the forces in combat. Therefore, given its importance, these countries began to try to raise the morale of the workers through propaganda methods such as the one seen in the image.
Scientists should definitely use evidence - and they collect this evidence though especially designed experiments. Based on their data and assumptions they build models which they then test, but they can base their conclusions based on the models too.
What they should not do is based the conclusions on opinions, because opinions are not imparcial- they can state them as opinions, but not as conclusions.

The reason why one case of influenza does not confer lifelong immunity is that the virus tends to mutate overtime which makes it unrecognizable to the immune system.
<h3>Why is it difficult to get immunity to influenza?</h3>
Influenza is caused by a virus which tends to mutate overtime in order to stay ahead of medical technology.
As a result, this mutation makes the original virus unrecognizable to the immune system which would then be unable to fight it.

False; stop sympathizing with Delmar and to withhold any sort of positive
reinforcement to his pain behaviors would make him bear the pain.
How positive reinforcement works?
Positive reinforcement in operant conditioning refers to the addition of a reinforcing stimulus after a behavior that increases the likelihood that the behavior will occur again in the future. An action's response or behavior will get stronger if a positive result, circumstance, or reward follows it. Here Delmar needs positive reinforcement for reduction in pain.
Positive reinforcement's impact on motivation is another factor contributing to its appeal as a teaching strategy. Positive reinforcement may provide you the boost in motivation you need to accomplish the goals you set, whether you are using it on your staff to reward good work or on yourself to work toward personal goals. Delmar should use positive reinforcement against his pain behaviour.
