Question

look at the word theories in the passage below. leonardo da vincis most famous painting is the mona lisa. many people wonder who the woman in the painting is. most believe she is lisa del giocondo, the wife of a rich trader. but there are different theories. some believe that da vinci painted her based on one of his students. others think she is leonardo da vincis mother. what is the meaning of theory as used in the passage? a game a guess a rule

Explanation:

In the passage, after stating the common belief that the woman in the Mona Lisa is Lisa del Giocondo, it presents other ideas like "Some believe...", "Others think...". These are not based on solid, proven facts but rather are different suppositions. A "guess" fits this context as it represents an opinion formed without definite knowledge, similar to these alternative views about the identity of the woman in the painting. A "game" has no relation to the context of different views on the painting's subject, and a "rule" implies a more established and fixed principle which these alternative ideas are not.

Answer:

B. a guess
