Read the passage from When Birds Get Flu and Cows Go Mad! by John DiConsiglio
Japan, for example, tests a sample from every cow that will be used for food. The meat is kept in refrigerators until the test
comes back negative. Most European nations test about 70 percent of their cows.
But in the U. S., only about 650,000 of the 35 million cattle slaughtered each year are tested.
The author most likely includes a signal word so that the reader will recognize?

Explanation:

I'm not quite sure if this is correct, but I did a process of elimination;

'That the passage's tone is being defined' doesn't sound quite right

'That the passage's cause is being defined' is incorrect because the passage is explaining the cause's effects

And 'that the situation is resolved' is wrong because when I took the test it wasn't the right answer. Hope this helps (?)
