Question

How is ""A Brief Study of Guts"" organized?
Cause and effect
Chronological order
Fact by fact
Problem-solution

Answer 1

Note: this is the original passage the question is referring to

You may not know this, but you are home to a colony of bacteria. You may also not know it, but the health and happiness of that colony of bacteria have a direct effect on your own health and happiness. In short, if we are what we eat, then we may need to make bacteria part of our balanced breakfast.

Microbes are single-celled organisms. They are literally everywhere. Microbes are in the air we breathe, on the surfaces of everything we touch, and inside our bodies. Microbes can be bacteria, fungi, protozoa, or viruses.

A few years ago, scientists began studying the microbial life of our stomachs. Called The American Gut project, this study aims to understand the life of the bacteria that live in our digestive system. According to an article in the New York Times by Michael Pollan, the goal is to gather information on the types and amounts of bacteria in the human gut. Scientists want to describe what a normal healthy microbe and human relationship should look like inside our digestive system. While the research is still in the very early stages, scientists have learned the following:

The strongest and healthiest microbe systems are those with a lot of variety.
The guts of Americans have much less variety than the guts of other populations.
Diets that include a lot of processed foods support less variation in bacteria.

Answer 2

anyway, try to go through each of the organizational methods and see which one best applies to the structure being presented

Cause and effect ---> does the passage present a cause, and then describe the effect?
Chronological order ---> does the passage describe a series of events, organized by time?
Fact by fact ---> does the passage present a series of facts, but is not categorized by the other methods?
Problem-solution --> does the passage present a problem, then the solution to that problem?
