Difficulty: EasyRhetorical Synthesis: Introduction and Definition

While preparing a presentation on environmental biotechnology, a student took the following notes:
* Phytoremediation is a clean-up method that uses living plants to remove, transfer, or stabilize environmental contaminants in soil and water.
* It serves as an eco-friendly alternative to harsh chemical treatments or excavation.
* Certain plants, such as sunflowers and willow trees, are highly effective at absorbing heavy metals.
* The term was first proposed in 1991 by plant biologist Ilya Raskin.

The student wants to introduce phytoremediation to an audience unfamiliar with the concept. Which choice most effectively uses information from the given notes to accomplish this goal?

  1. A
    First proposed in 1991 by Ilya Raskin, phytoremediation can utilize plants like sunflowers and willow trees to absorb heavy metals.
  2. B
    Certain plants, such as sunflowers and willow trees, are highly effective at absorbing heavy metals from contaminated soil.
  3. Phytoremediation is an eco-friendly clean-up method that uses living plants to remove or stabilize environmental contaminants in soil and water.Answer
  4. D
    Serving as an alternative to excavation, phytoremediation was first proposed by biologist Ilya Raskin in 1991.

Answer

Phytoremediation is an eco-friendly clean-up method that uses living plants to remove or stabilize environmental contaminants in soil and water.
The correct answer effectively introduces the term to an unfamiliar audience by defining it as a clean-up method that uses living plants to remove or stabilize environmental contaminants. This provides the fundamental explanation required for someone who does not know the concept.

Step-by-Step Solution

1
Identify the student's primary objective from the prompt.
The student wants to introduce phytoremediation to an audience that is unfamiliar with the concept.
Understanding the specific rhetorical goal is necessary to filter the relevant notes.
2
Determine what information is required to introduce a concept to an unfamiliar audience.
An effective introduction requires a clear definition explaining what phytoremediation is.
An audience unfamiliar with a term needs to know its basic meaning before learning other details like its history or specific examples.
3
Evaluate the choices to find the one that defines the term.
The option defining phytoremediation as an eco-friendly clean-up method using living plants to remove or stabilize contaminants is the only choice that provides a definition.
This choice synthesizes the definition directly from the first bullet point, successfully introducing the concept.
