read the passage.
the pet food industry
you have just adopted a pet, and youre at a pet supply store. you are overwhelmed by the never - ending sea of colorful pet food packages. some bags claim that theyre organic or natural, but what does that mean? and then there are the stacks of canned food, boasting loudly of their superior contents. whats the difference among these foods? does it matter what you feed your dog or cat? yes, it does matter. and the text on the package does not always tell the whole story.
according to the american pet products association (appa), 68 percent of u.s. households own a pet. the appa also estimates that u.s. pet owners will spend $25 million on pet food in 2016. but the contents, quality, and cost of foods vary dramatically. a foods national popularity does not necessarily equate to a healthy choice, especially when advertising plays such a heavy role in sales. to select the best nutritional match for your pet, it is important

the headings list, in sequence, the areas of most concern when looking for the right nutritional match for different kinds of pets.
each heading introduces a step in the manufacturing process of pet food and provides evidence of how faulty processes affect food quality.
the headings represent different perspectives on pet nutrition to present consumers with more objective information about pet food choices.
each heading presents an aspect of the pet food manufacturing and marketing process and explains how it affects the accuracy of information provided on pet food packaging.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: The claim is about pet food labels not telling the whole story, not about nutritional match for different pets. Eliminate.
• Option 2: The passage isn't focused on manufacturing process faults affecting quality. Eliminate.
• Option 3: The headings don't present different perspectives on pet nutrition for objective info. Eliminate.
• Option 4: The headings (though not shown, but from context) should relate to how manufacturing/marketing aspects affect label info accuracy, which ties to the claim about labels not telling the whole story. This fits.

Answer:

Each heading presents an aspect of the pet food manufacturing and marketing process and explains how it affects the accuracy of information provided on pet food packaging.
