The rules of inference (also known as inference rules) are a logical form or guide consisting of premises (or hypotheses) and draws a conclusion. A valid argument is when the conclusion is true whenever all the beliefs are true, and an invalid argument is called a fallacy as noted by Monroe Community College.
Answer:
(1) An author doing research for a book asked thousands of Americans what made them happy.
Explanation:
It's tempting to say that the main idea is the conclusion of the paragraph, which is stated in sentence (5). However, the main focus of the paragraph is more on the research on what makes American happy, which is detailed by the responses of the research subjects, as well as the conclusion of the research study. If (5) was the main focus, there would be more details about why most of the things that make you happy are simple and free or inexpensive or what the general research about this topic has been, instead of just one study in particular.
Troy Davis was not allowed to submit to the lie detector to prove his guilt before being executed, as a last resort to avoid lethal injection. His defenders accused the Court of racial discrimination.
Davis´s attorney, Stephen Marsh, has commented that the Georgia department of corrections rejected the request to take the polygraph test. However, until the last minute Davis, did not recognize himself guilty of the murder of police officer Mark McPhail in 1989.
In spite of the doubts about the sentence, lack of real evidence of Davis´s participation in that murder and numerous social protests, the supreme court of the United States rejected the last request of clemency.
In both cases we can infer, although the country fights in order to defeat the racism, is a currently present problem.
