For the following argument, do three things: (1) identify the terms of the argument, assigning them symbols; (2) set the syllogism out in standard AEIO form, marking the distributed terms with asterisks; and (3) say whether or not the argument is valid, explaining how one of the validity rules is violated if it is invalid.  If the argument is an enthymeme, complete it, if possible, to make come out valid.  (2 points for the symbolization, 4 points for standard form, 4 points for the evaluation, 10 points total) Some studious people aren’t friendly.  But people are friendly if they value other people.  So some people who value others aren’t studious.

For the following argument, do three things: (1) identify the propositions involved, assigning them symbols; (2) set the argument out in standard form either as a hypothetical or a disjunctive syllogism; and (3) say whether it is valid or not, indicating what type of argument it is: denying the necessary condition, affirming the disjunct, etc.  If there is a missing premise or conclusion, complete the argument, if possible, to make it come out valid.  (2 points for the symbolization, 4 points for standard form, 4 points for the evaluation, 10 points total) There can’t be a general economic recovery without people being willing to invest.  And let’s face it, people just aren’t willing.

Consider the following example of inductive reasoning: In September 2019, each student in Mrs. Newsome’s first grade class (Hank James Elementary in Woolett, Massachusetts) was given three 2 oz. scoops of ice cream: one vanilla, one chocolate, and one bubble-gum tutti frutti.  2 of the 26 students preferred chocolate, 4 preferred vanilla, and 20 preferred bubble-gum tutti frutti.  Researchers concluded that, with respect to ice cream flavors, American children prefer bubble gum tutti frutti to chocolate or vanilla. Consider the following modification of the argument, and indicate if it strengthens the argument (makes it more likely that the conclusion is true), weakens the argument (makes this less likely), or has no effect.  Then explain why you think this is so: It was concluded that children generally prefer bubble gum tutti frutti ice cream to chocolate or vanilla.

Complete the following argument by analogy in a plausible way by adding a comparison case and some known similarities.  Then indicate what seems to you the most significant relevant dissimilarity between the new case and the comparison case. new case:  High-speed internet service inferred similarity:  should be made available to all citizens at public expense.

Consider the following modification of the argument, and indicate if it strengthens the argument (makes it more likely that the conclusion is true), weakens the argument (makes this less likely), or has no effect.  Then explain why you think this is so: It was concluded that five times as many American children prefer bubble gum tutti frutti to vanilla, and twice as many prefer vanilla to chocolate.

For the following argument: Select symbols and be sure to define them accurately.  Put the argument into standard form as a hypothetical or disjunctive syllogism.  Identify the form (e.g., “affirming the necessary condition,” or “denying the disjunct”).  Determine whether it is valid or invalid.  If the argument has a missing premise or conclusion, complete the argument to make it come out valid, putting the added proposition in square brackets.  If you’ve made it this far in the course, then you must be serious about logic.  And you can’t be serious about logic unless you love it.  It follows then (or does it?) that you’ve got to love logic if you’ve made it this far.
