Answer:
1. B. Shift. There are night guards, or dog guards in this scenario, during a night shift.
2. C. We know Kato can't be a bad worker, because he only rides the ferris wheel when he's off-duty. Kato also cannot get dizzy on the ferris wheel, reading that he can ride it for hours. Lastly, Kato doesn't eat a lot during his shift, because nothing in the text states that.
3. A. a section. Not the workplace, because once again Kato is off-duty when he rides the ferris wheel. The other answers don't make sense.
4. D. Although it does talk about the other answers in the paragraph, it mainly talks about the life of an amusement park dog.
Hope this helps!
