Answer:
Explanation:
No one thinks it will be easy. Gun violence in America is one of those problems that can feel truly hopeless. The U.S. has only 4.4% of the world’s population, yet it accounts for roughly 42% of the world’s guns, according to the comprehensive 2007 Small Arms Survey. And roughly 31% of the world’s mass shooters are American, according to a University of Alabama study. Even as mass-shooting deaths mount, our Second Amendment has made gun rights a third-rail issue: roughly 90% of Americans agree on “common-sense” solutions like universal background checks, yet absolutists stand in the way of any meaningful action.
The meaning of the phrase cost-effective in the first paragraph of this passage is C. getting the most for the money you spend.
If you insulate and seal air leaks in your home on time, you won't have to think about that in the future. Thus, if you pay a lot of money now, you will save a lot more in the future than if you didn't insulate, and then had to fix stuff around the house all the time, which would waste so much of your money.
