Here's why:
* Incomplete Passage: The sentence is a single statement about the advantages of using plastic for containers. It doesn't offer any contrasting information about other materials.
* No Clear Purpose: The sentence simply states a fact about manufacturer preference. It doesn't provide any argument or explanation for why this preference exists.
To assess the use of compare-and-contrast and its purpose, we need a more complete passage. For example, the passage could be expanded to:
* Compare: Plastic to other materials like glass, metal, or cardboard, highlighting advantages and disadvantages of each.
* Contrast: The benefits of using plastic for container manufacturing with the potential environmental concerns associated with its production and disposal.
Once we have a complete passage with contrasting information, we can analyze how the compare-and-contrast pattern serves its purpose. For instance, it could:
* Inform readers: Provide a balanced understanding of different container materials and their associated pros and cons.
* Persuade readers: Argue for or against the use of plastic containers by highlighting its strengths or weaknesses compared to alternatives.
* Analyze a problem: Investigate the complex factors that influence the choice of container materials, including economic, environmental, and practical considerations.
Please provide the complete passage so I can assist you in analyzing its organizational pattern and purpose.
