A team of engineers claims that their new water-filter design removes a wider range of contaminants than current home filters.
Which finding, if true, would most strongly support the team's claim?
- A
The new filter is similar in size to current home filters.
- Bcheck_circle
Laboratory tests with the new filter and a leading current home filter showed that the new design removed several classes of contaminants that the current filter did not.
- C
Many home filters are sold each year.
- D
Some filters use activated carbon as a filtration medium.
Explanation
A directly compares contaminant removal between the new and current filters. B, C, and D are tangential.
