"If the law of gravity is correct, things fall toward the center of the earth when dropped; things do fall toward the center of the earth when dropped; therefore the law of gravity is correct." is an example of:

    { 1 } - hypothetical syllogism.
    { 2 } - modus ponens.
    { 3 } - disjunctive syllogism.
    { 4 } - an invalid inference.
    { 5 } - modus tollens.

4 is correct!


"If the law of gravity is correct, things fall toward the center of the earth when dropped; things do fall toward the center of the earth when dropped; therefore the law of gravity is correct." is an example of:

    { 1 } - hypothetical syllogism.
    { 2 } - modus ponens.
    { 3 } - disjunctive syllogism.
    { 4 } - an invalid inference.
    { 5 } - modus tollens.

This is the inductive method of verifying scientific laws, which invalidly asserts the consequence of a modus ponens argument.
