Question

select the word that means real.
in 2000, the owners of a painting asked scientists to examine it. they had been told it was painted by van gogh, a famous artist. but they suspected it was a fake. the experts used x - rays to \see\ the canvas. from that, they concluded the painting was not authentic. the canvas was different from the type that van gogh had used.

Explanation:

To solve this, we analyze the context. The painting was suspected to be a fake, and the experts concluded it was not "authentic". In this context, "authentic" means real (as opposed to fake). The other key word from the passage related to "real" is "authentic" because the owners wanted to know if the painting was a real Van Gogh (not a fake), and the experts determined it was not authentic (so not real). So the word meaning real here is "authentic".

Answer:

authentic
