Use the given information to make a logical conclusion, if possible. If a logical conclusion is not possible, choose "no logical conclusion possible."

If IF_CLAUSE, then THEN_CLAUSE. capitalize(IMPLICATION[ TYPE ]).

SOLUTION

- capitalize(CONCLUSION[TYPE])
- No logical conclusion possible

Identify the hypothesis, the conclusion of the first sentence, and the second sentence.

$("#if-clause").addClass("hint_blue"); $("#then-clause").addClass("hint_green"); $("#second-sent").addClass("hint_purple");

Does the second sentence refer to the hypothesis of the first sentence, or the conclusion of the first sentence?

The second sentence refers to the hypothesis of the first sentence, because they both talk about whether or not IMPLICATION[0].

Does the second sentence state the hypothesis, or the opposite of the hypothesis?

The second sentence refers to the conclusion of the first sentence, because they both talk about whether or not IMPLICATION[1].

Does the second sentence state the conclusion, or the opposite of the conclusion?

The second sentence states the hypothesis of the first sentence.

Because the second sentence states the hypothesis of the first sentence, the second sentence implies the first sentence.

Since we are implying the original statement, we can conclude the conclusion of the first statement.

The second sentence states the conclusion of the first sentence.

Because the second sentence states the conclusion of the first sentence, the second sentence implies the converse of the first sentence.

Converses are not logically equivalent to their original statements, so we cannot form a logical conclusion.

The second sentence states the opposite of the hypothesis of the first sentence.

Because the second sentence states the opposite of the hypothesis of the first sentence, the second sentence implies the inverse of the first sentence.

Inverses are not logically equivalent to their original statements, so we cannot form a logical conclusion.

Because the second sentence states the opposite of the conclusion of the first sentence, the second sentence implies the contrapositive of the first sentence.

Since the contrapositive is implied by the first sentence, the second sentence implies the opposite of the hypothesis.

Thus, the answer is "SOLUTION"

("If "+HYP_A+", then "+CONC_B+".") : "No logical conclusion possible."

Use the given information to make a logical conclusion, if possible.

If HYP_A, then CONC_A. If HYP_B, then CONC_B.

SOLUTION

- If HYP_A, then CONC_B.
- If HYP_A, then HYP_B.
- If CONC_A, then CONC_B.
- No logical conclusion possible.

Identify the first hypothesis, the first conclusion, the second hypothesis, and the second conclusion.

$( "#hyp_a" ).addClass( "hint_blue" ); $( "#conc_a" ).addClass( "hint_green" ); $( "#hyp_b" ).addClass( "hint_red" ); $( "#conc_b" ).addClass( "hint_purple" );

Do the two sentences come in the form "If P, then Q. If Q, then R", where first conclusion and second hypothesis are the same?

In other words, do the sentences look like `\blue{P}\implies \green{Q}`. `\red{Q}\implies \purple{R}`?

Yes. Because the middle two statements both say HYP_B, we can chain the statements together: `\blue{P}\implies\green{Q}\implies\purple{R}` or "HYP_A"`\implies`"CONC_A"`\implies`"CONC_B".

We can now remove the middle statement, and arrive at the conclusion "HYP_A"`\implies`"CONC_B". So, the answer is "If HYP_A, then CONC_B."

No. So, we cannot form a logical conclusion.
