What is one example from the passage that provides evidence to support the central idea of the text?
"The researchers, led by plant geneticist Philipp
Simon, haven't limited themselves to the color
orange."
"They've selectively bred a rainbow of carrots-
purple, red, yellow, even white."
"Red carrots derive their color mainly from lycopene,
a type of carotene believed to guard against heart
disease and some cancers."
O "Purple and yellow carrots were eaten more than
1,000 years ago in Afghanistan and 700 years ago in
western Europe,' says Simon."
