Question

1. what is a discipline as referenced in paragraph 3?

a a specific area of study
b a desirable gene
c a scientific hypothesis
d a method of punishment

1. how does the section \changing plants isnt new\ develop the authors’ claims about genetic alteration?

a by offering background information about the origin and development of genetic alteration
b by providing evidence that shows it is safe for people to consume plants produced by genetic alteration
c by emphasizing that genetic alteration has modernized what farmers have been doing for thousands of years
d by identifying which specific food qualities genetic alteration seeks to improve

1. select two quotations from the text that support the authors’ claim that genetic alterations can improve the qualities of food.

a “it is estimated that 60 to 70 percent of all processed foods available on store shelves contain gmo ingredients, particularly corn or high fructose corn syrup, soybeans, and cottonseed or canola oils.” (paragraph 1)
b “but parsley is resistant to frost. it has built-in antifreeze chemicals that protect it from even heavy frost.” (paragraph 5)
c “soybeans have been genetically modified to resist disease and pests, or to produce more protein, vitamins, and fat.” (paragraph 11)
d “for example, general mills now sells cheerios in a non-gmo form in europe, while the cheerios sold in the u.s. still contain cornstarch, sugar, and vitamin e in genetically modified forms.” (paragraph 13)
e “3. improved nutrition, such as higher-than-natural levels of vitamin a, enhances health and quality of life for some people.” (paragraph 14)

1. how do the authors order ideas to develop their points about gmo foods?

a the authors relay anecdotes of farmers successfully using genetic alteration to invent new plants.
b the authors explain the science of genetic alteration and its potential impacts.
c the authors cite research and data about the negative health effects of genetically engineered crops.
(option d is partially visible and omitted)

Explanation:

Question 20

To determine the meaning of "discipline" in the paragraph (context related to study areas), option A ("a specific area of study") fits as disciplines in academia are study areas. Option B is about genes, C about hypotheses, D about punishment—none match the study - related context.

The section "Changing Plants Isn’t New" likely gives background on how genetic alteration has roots in traditional farming (modernizing what farmers did for years). Option A is about origin/development details (not the main focus here), B about safety (not the section's focus), D about specific food qualities (not the section's aim). So C is correct.

We need quotes showing genetic alteration improves food qualities.

• Option C: "Soybeans have been genetically modified to resist disease and pests, or to produce more protein, vitamins, and fat." shows improvement (more nutrients, resistance).
• Option E: "3. Improved nutrition, such as higher - than - natural levels of vitamin A, enhances health and quality of life for some people." directly states improved nutrition.

Option A is about GMO prevalence, B about parsley's natural frost resistance, D about Cheerios' GMO/non - GMO forms—these don't show improvement.

Answer:

A. a specific area of study
