黃金閱讀 Meteorite Impact and Dinosaur Extinction - 英檢

最後一題
14.要選三個

○Scientists had believed for centuries that meteorite activity influenced
evolution on Earth.
○An iridium-enriched sediment layer and a large impact crater in the Yucat
provide evidence that a large meteorite struck Earth about 65 million years
ago.
○The site of the large meteorite impact at the end of the Cretaceous period
was identified in 1990.
○Large meteorite impacts, such as one at the end of the Cretaceous period,
can seriously affect climate, ecological niches, plants, and animals.
○There have also been large meteorite impacts on the surface of the Moon,
leaving craters like Tycho.
○Meteorite impacts can be advantageous for some species, which thrive, and
disastrous for other species, which become extinct.

我想問3為什麼不對呢?

文中不是提到：(Paragraph 3)By 1990 geologists had located the impact site
itself in the Yucat region of Mexico.
