B is the correct answer because A makes the reader believe that the two Notaries preferred ether of the options rather than specifying they each chose only one type.
Okay, lets start from the beginning. I'm going to assume the worksheet means/is asking how long/short the sound would be from the object. So...
1) Light bulb - Long
2) Bricks/Cinderblocks - Short
3) Hair Dryer - Long
4) Swimming - Long
5) Whistle - Could potentially be both, but most likely short.
6) Crying/Wailing - Long
7) Fencing - Could potentially be both, but most likely short.
8) Grilling - Could potentially be both, but most likely long.
9) Flies/Bug - Could potentially be both, but most likely long.
10) Smiling- Short
11) Eating Pie/Pie in General - Could potentially be both, but most likely short.
12) Jumping off a cliff. Could potentially be both, but most likely long.
Hope that helps.
What? This doesn't make sense..
