Question

but was this gray whales appearance really a freak occurrence, or is there
based on the text, what was so shocking about the may 8, 2010, sighting of a gray whale in
the mediterranean sea?
that particular gray whale was last spotted off the coast of california.
gray whales had not lived in the atlantic ocean for centuries.
in three weeks, the gray whale had made its way to israel from spain.
biologists believed that gray whales had been extinct since the 1700s.

Explanation:

The text likely discusses the normal habitat range of gray whales. Gray whales were thought to have a certain historical range. If they had not lived in the Atlantic (where the Mediterranean is connected) for centuries, a sighting there would be shocking. The first option about a specific whale's last - spot location doesn't explain the general shock of the species' appearance. The third option about movement within a short time (three weeks) is less relevant to the overall shock of the species' presence. The fourth option is incorrect as gray whales were not believed to be extinct (they were endangered).

Answer:

Gray whales had not lived in the Atlantic Ocean for centuries.
