"Knowledge is power" is a famous proverb which states that a person with knowledge can outwit physical strength of any other person.
What you can infer from this passage is that publication of "Ann Landers" ceased in 2002 (D).
Indeed, the text tells us that Esther Lederer, the legal author of "Ann Landers," died in 2002 without passing on the rights to her pen name—
which is also the name of her column—to anyone else ("she chose not to have another writer assume the pen name"). Since she did not allow any other writer to use the "Ann Landers" name, we can assume she didn't pass on the column's rights either.
Explanation:
Mass is a measure of the amount of matter in an object. Mass is usually measured in grams (g) or kilograms (kg). ... An object's mass is constant in all circumstances; contrast this with its weight, a force that depends on gravity. Your mass on the earth and the moon are identical.
