Janell has discovered in her literature review that people often learn by imitation and observation (termed social learning). For example, when children see an adult behave violently toward a doll, they often imitate this violent behavior. Janell decides to do a study in which children who are initially afraid of snakes either view an adult playing with a snake or view nothing at all. She thinks that the children who view an adult playing with a snake will be more likely to later pet a snake than children who view nothing at all. Which of the following statements best represents the hypothesis? a. "Social learning refers to the idea that people often learn by imitation and observation."
b. "Children who view an adult playing with a snake will be more likely to later pet a snake than children who view nothing at all."
c. "Past research has found that when children see an adult behave violently toward a doll, they often imitate the violent behavior."
d. All of the above can be considered hypotheses.

“dear sir: it is with great reluctance, i trouble you on a subject, which does not fall within your province; but it is a subject that occasions me more distress, than i have felt, since the commencement of the war; and which loudly demands the most zealous exertions of every person of weight and authority, who is interested in the success of our affairs. i mean the present dreadful situation of the army for want of provisions, and the miserable prospects before us, with respect to futurity. it is more alarming than you will probably conceive, for, to form a just idea, it were necessary to be on the spot. for some days past, there has been little less, than a famine in camp. a part of the army has been a week, without any kind of flesh, and the rest for three or four days. naked and starving as they are, we cannot enough admire the incomparable patience and fidelity of the soldiery, that they have not been ere this excited by their sufferings, to a general mutiny or dispersion. strong symptoms, however, discontent have appeared in particular instances; and nothing but the most acitive efforts every where can long avert so shocking a catastrophe.” what’s the central idea?
