Question

the graph shows the antibiotic resistance of two species of enterococci. which evidence from the graph supports the argument that enterococcus faecalis shows a low resistance to most of the tested antibiotics? higher resistance to amoxicillin by e. faecium than e. faecalis equal percentages of e. faecium and e. faecalis resistant to linezolid the change in the percent resistant to different antibiotics for both e. faecalis and e. faecium overall lower percentages of e. faecalis resistant to antibiotics than e. faecium

Explanation:

The argument is about E. faecalis having low resistance. Option D directly compares the overall percentages of resistance between E. faecalis (lighter - colored bars) and E. faecium (darker - colored bars). If E. faecalis has overall lower percentages of resistance across most antibiotics (as seen by comparing the heights of the light - colored bars to the dark - colored bars for each antibiotic), it supports the claim that E. faecalis shows low resistance.

• Option A only compares resistance to amoxicillin and doesn't address most antibiotics.
• Option B (equal resistance to linezolid) is a single - point comparison and not about most antibiotics.
• Option C (change in percent resistant) is too vague and doesn't specifically show low resistance of E. faecalis to most antibiotics.

Answer:

D. overall lower percentages of E. faecalis resistant to antibiotics than E. faecium
