## Why these answers are right

**27. NO.** Paragraph A says that instead of making any judgments himself about a strike, DeJesus had decisions fed to him through an earpiece. He only announced what the system decided, so he did not share decision-making with it, and the answer is NO.

**28. YES.** Paragraph D reports that players complained about strange calls in the first season and that, in response, MLB decided to tweak the dimensions of the zone. Tweaking dimensions means amending its size after criticism, so the statement agrees with the writer: YES.

**29. NOT GIVEN.** Paragraph D gives MLB's claim that the device is near-perfect and precise to fractions of an inch, but no cost is mentioned and nothing suggests MLB wants to justify spending. The writer's view on this is NOT GIVEN.
