Question 1 of 200
Read the following passage and answer the question:
"The human microbiome, consisting of trillions of microorganisms living in and on the
human body, plays a crucial role in digestion, immune function, and even mental
health. Recent studies have shown that individuals with diverse gut bacteria tend to
have stronger immune responses and lower rates of autoimmune diseases. Conversely,
a lack of microbial diversity has been linked to conditions such as obesity, diabetes,
and depression. Researchers believe that modern lifestyles, including the overuse of
antibiotics and highly processed diets, have reduced microbial diversity in populations
worldwide."
Which of the following best states the main idea of the passage?
A. Antibiotics are the primary cause of reduced microbial diversity worldwide
B. The human microbiome is important to health, and modern lifestyles may reduce its
diversity
C. People with diverse gut bacteria never get sick
D. Processed diets are the only factor affecting the microbiome
Correct Answer: B
Explanation: The passage discusses the importance of the microbiome for health
and connects modern lifestyles to reduced diversity. Options A and D are too
narrow, and C is an absolute statement not supported by the text.

,discovery led to the development of penicillin, the first widely used antibiotic. Before
penicillin, even minor infections could be fatal. By the 1940s, mass production of
penicillin had begun, saving countless lives during World War II. However, Fleming
himself warned that misuse of antibiotics could lead to resistant bacteria, a prediction
that has proven alarmingly accurate."

mental health, a sense of purpose, and stronger community connections. Some shelters
even offer training programs that allow volunteers to develop skills in veterinary care
and animal behavior."
