Questions of policy inevitably incorporate questions of fact. True or False

True Or False (2’×5=10’) Directions:Read the following 6 short passages, and do the True (T) and False (F) based on each passage. 1. Bodily contact is of interest since it is the most primitive kind of social act, and is found in all animals. In addition to aggressive and sexual contacts there are various methods of influence, as when others are pushed, pulled or led. There are symbolic contacts, such as patting on the back, and-the various ways of shaking hands. 2. Bodily posture is another signal which is largely involuntary, but which can communicate important social signals. There are distinctive “superior” (or dominant) and “inferior” (or sub. missive) postures. 3. Gestures are movements of hands, feet or other parts of the body. Some are intended to communicate definite messages; others are involuntary social cues which may or may not be correctly interpreted by others. 4. Head-nods are a rather special kind of gesture, and have two distinctive roles. They act as reinforcers, i.e. they reward and encourage what has gone before, and can be used to make another talk more, for example. 5. Facial expression can be reduced to changes in eyes, brows, mouth, and so on. The face is an area which is used by animals to communicate emotions and attitudes to others; for humans it does not work so well since we control our facial expression, and may smile sweetly while seething within. 1. ____ Symbolic contacts include patting on the back and shaking hands.

True or false 1. Most universities and scholarship programs in the west require one recommendation letter as part of the application process. 2. References are usually written by your friends and parents. 3. A reference letter 
is more general in nature than a letter of recommendation. 4. In a letter of recommendation, the writer should know the candidate well enough to evaluate their abilities and details the candidate's accomplishments and skills that make him a strong contender based on the writer’s personal experience with this candidate. 5. A letter of reference should be addressed to a specific recipient. 6. Recommendation letters help to shed light on the “full package” that is difficult to fully convey in a resume and personal statement. 7. For most job applications, a well-written resume and cover letter are more than enough. However, certain industries or companies may require a letter of recommendation in addition to these basic essentials. 8. The conclusion should make a clear statement of reference that flows logically from the points made in the assessment part of the letter.
