In chapter 1, for example, after discussing mass and density, they have a brilliant little "Think about this:" section that says, "Think about this: If you had 1,000 grams of feathers and 1,000 grams of the metal lead, which one would you use to fill your pillow? Even with both samples having the same mass, it is hard to imagine having much fun at a pillow fight if the pillow were filled with lead!" Don't forget, readers, this is on the first page of chapter 1. I suffered through 13 chapters, 187 pages SO YOU DON'T HAVE TO!! This book is NOT your friend when you're short on time. Answer:
A:
output: No
