a) passage 2 offers an evaluation of the significance
of the research discussed in passage 1.
b) passage 2 suggests a modification to the
methodology described in passage 1.
c) passage 2 uses concrete examples to illustrate
concepts considered in passage 1.
d) passage 2 takes a dismissive stance regarding the
findings mentioned in passage 1.
50
both passages make the point that teixobactin could
be useful in
a) standardizing the future development of
antibiotics produced in laboratory
environments.
b) combating infections that are no longer
responding to treatment with other antibiotics.
c) controlling the spread of pathogenic soil fungi.
d) shaping a new method of studying the
effectiveness of antibiotics.
51
information in passage 2 best supports which
conclusion about the mice in the experiment
described in passage 1?
a) exposure to teixobactin made them less
susceptible to subsequent upper respiratory tract
infections.
b) gram-positive bacteria enhanced the
effectiveness of teixobactin against their upper
respiratory tract infections.
c) their upper respiratory tract infections were
likely not caused by gram-negative bacteria.
d) teixobactin attacked the proteins of the bacteria
that caused their upper respiratory tract
infections.

Explanation:

Question 49

To solve this, we analyze each option:

• Option A: Passage 2 likely evaluates the significance of Passage 1's research (about teixobactin). This is common in paired passages where one assesses the other's importance.
• Option B: There's no indication of methodology modification.
• Option C: Passage 2 doesn't use concrete examples to illustrate Passage 1's concepts.
• Option D: Passage 2 doesn't dismiss Passage 1's findings.

Analyze each option:

• Option A: The passages don't focus on standardizing antibiotic development.
• Option B: Teixobactin is useful against infections resistant to other antibiotics (a common theme in antibiotic research).
• Option C: Teixobactin targets bacteria, not soil fungi.
• Option D: It's about treating infections, not studying antibiotic effectiveness.

For the mice experiment in Passage 1:

• Option A: The passage doesn't say teixobactin reduced susceptibility to subsequent infections.
• Option B: Gram - positive bacteria's role in enhancing teixobactin's effect isn't supported.
• Option C: Teixobactin targets gram - positive bacteria, so if it worked, the infections were likely not from gram - negative bacteria. This is logical.
• Option D: Teixobactin targets bacterial cell walls, not proteins.

Answer:

A) Passage 2 offers an evaluation of the significance of the research discussed in Passage 1.
