Now let’s look at a longer argument and analyze the evidence.

In the following essay from the New York Times, Frank Bruni makes an argument concerning invasive plants and animals. Let’s see if we can figure out what the claim is and what evidence Bruni uses to support the claim. In a longer text such as this, you may find several claims that may be supported with evidence. In this activity, you are going to be looking only for the major claim in the text. You are looking, in other words, for the main point.

As you read, consider whether the sentences highlighted in blue qualify as the major claim. Consider also whether the sentences highlighted in pink qualify as important evidence. You will be asked about the major claim and the evidence after you finish reading.

Malicious but Delicious

By FRANK BRUNI
AUSTIN, Tex.

For your personal health, you should probably eat more vegetables.

But for the future of civilization as we know it?

More pork. Feral hogs, to be exact.

They’re multiplying like mad — like rabbits with hooves, tusks and an epic sense of entitlement — especially here in Texas, where an estimated 2.6 million of them routinely desecrate farmland by rooting up crops, decimate reptile populations by snacking on them, devour feed meant for livestock and probably do some other pernicious thing beginning in “de-” that won’t come to me right now.

Destroy enclosures! That’s it. Feral hogs have been known to chew and stomp their way into suburban yards and even onto Army bases, said Richard Heilbrun, a biologist with the Texas Parks and Wildlife Department. “And when you have a military installation with a fence problem,” he told me, “you have a national security problem.”

You also have an excellent reason to turn these hammy hellions into dinner.

That’s what the chef Ned Elliott was up to when I dropped by his Austin restaurant, Foreign & Domestic, on Friday. He and several other cooks were using deboned flesh from two feral hogs for porchetta, the beloved Italian roasted pork dish. They planned to serve it, along with giant Asian tiger prawns and Himalayan blackberries, at a special feast at the restaurant staged in cooperation with the Texas chapter of the Nature Conservancy.

The event had a saucy sobriquet, “Malicious but Delicious,” and a serious mission: to raise people’s awareness of, and ideally whet their appetites for, the bullies of the ecosystem, more formally known as invasive species, invasives for short. In certain areas of the United States, the hogs, the prawns and the blackberries qualify.

“They’re aggressive,” Elliott told me, providing a tidy case for their digestion.

All you principled environmentalists out there, you’re being lax. Your recycling is admirable and your farmers’ market patronage appreciated, but there’s a whole class of animals, fish and plants that are throwing the earth out of balance, and it’s time you turned not just your attention but also your bicuspids and incisors toward them.

They aren’t evil in and of themselves. They just don’t play so well with others, and proliferate ostentatiously. Many aren’t even meant to be part of the habitats they now maraud across, but thanks to human meddling, they ended up there, then got bossy about it.

“It’s as if you came home from work and a bunch of people had moved into your house,” said Laura Huffman, the Texas director of the Nature Conservancy. “Maybe they’re nice enough, but they’re still eating all your food and sitting on your furniture, and that’s going to disrupt the way your family lives.

She was referring not only to hogs and tiger prawns but also to European green crabs, now common in Maine, where they prey on unsuspecting scallops.

Also Asian carp, the thuggish mobsters of the Mississippi, though maybe not for long. There’s been talk of rebranding them as “Kentucky tuna.”

Edible invasives are cataloged on a Web site aptly titled Eat the Invaders. It reflects a slowly growing awareness of the problem and a fledgling effort by ecologically minded chefs to address it.

In New York not long ago, the chef Kerry Heffernan prepared Asian carp and lionfish, which pose a ferocious threat from the Caribbean to the Carolinas, for a dinner at the James Beard House. At Miya’s Sushi in New Haven, Bun Lai regularly promotes such invasives as Asian shore crabs and burdock, a plant whose root is a delicacy in Japan. . . .

While Texans have accelerated their killing of hogs to about 30 percent of the population annually, that still allows for a doubling of the population over a five-year period. And that underscores the strange blind spots in the ways of us conscientious omnivores, who congratulate ourselves on foraging and on nose-to-tail eating while failing to chow down adequately on an entire breed just begging to be bacon.

Our first step in analyzing this argument is to decide on the claim. Below are all of the passages that are highlighted in blue. Click the sentence that you think is the major claim made in this argumentative essay.

A. “There’s a whole class of animals, fish and plants that are throwing the earth out of balance, and it’s time you turned not just your attention but also your bicuspids and incisors toward them.”
Correct! The major claim is about the destructiveness and also the deliciousness of “invasives.” The sentence about disrupting the family is part of an analogy supporting the claim but is not itself the major claim. The sentence about a growing awareness of the problem relates to a Web site that deals with eating invasives; it relates to the major claim, but the “whole class of animals” is the closest to being a statement of the major claim of the essay.

B. Invasives are like strangers who have moved into your home, and “that’s going to disrupt the way your family lives.”
Try again.

C. “[The Web site “Eat the Invaders”] reflects a slowly growing awareness of the problem and a fledgling effort by ecologically minded chefs to address it.”

Bruni states the claim in a rather indirect way.

Bruni: “[T]here’s a whole class of animals, fish and plants that are throwing the earth out of balance, and it’s time you turned not just your attention but also your bicuspids and incisors toward them.”

Before you match the claim with evidence, let’s restate the claim in simpler language. Which of the statements below most accurately matches the meaning of Bruni’s statement?

A. Certain plants and animals are causing problems for our teeth.
Try again.

B. When the earth is out of balance, both your attention and your chewing will suffer.
Try again.

C. We should kill and eat more invasives.
Correct! Although Bruni does not mention “killing” the invasives in the sentence above, it is implied. (We are not going to eat them if someone hasn’t killed them.)

Now, let’s analyze the evidence that supports this claim.

You can check it by using a test frame. The “frame” is the claim connected to the evidence with the word because.

The frame you will use is “We should kill and eat more invasives because _______________.” 

If the evidence makes sense when you put it into this frame, it is probably good evidence.

Let’s try out the first passage highlighted in pink to see if it will qualify as evidence. Here it is in a test frame with the claim.

We should kill and eat more invasives because feral hogs have been known to chew and stomp their way into suburban yards and even onto Army bases.

Does this sentence make sense? Is the destruction of yards and fences on Army bases a reason to kill feral hogs and eat them? Click to choose your answer.

a. Yes, this statement qualifies as evidence.
Correct! This is evidence for part of the claim that invasives should be killed. It doesn’t mention eating them, but the first step in an argument for eating invasives is to make a case for killing them.

b. No, this statement does not quality as evidence.
Try again.

Put the rest of the evidence in the frame. For each passage of possible evidence, select the button that reflects your answer.

1. We should kill and eat more invasives because some chefs “planned to serve [feral hog], along with giant Asian tiger prawns and Himalayan blackberries, at a special feast.”

a. Yes, this statement qualifies as evidence.
Correct! The connection between the claim and this evidence is not explicitly stated. However, the fact that chefs are making a special dinner using invasives implies that the invasives make good eating and therefore supports part of the claim, “We should eat them because they taste good.”

b. No, this statement does not quality as evidence.
Try again.

2. We should kill and eat more invasives because “Recycling [by environmentalists] is admirable and [their] farmers’ market patronage [is] appreciated.”

a. Yes, this statement qualifies as evidence.
Try again.

b. No, this statement does not quality as evidence.
Correct! It is nice of Bruni to acknowledge what environmentalists already do, but he is mentioning their efforts to set up an additional obligation for them. This statement helps Bruni compose his argument, but it is not evidence to support the claim that we should kill and eat invasives.

3. We should kill and eat more invasives because “they just don’t play so well with others, and proliferate ostentatiously.”

a. Yes, this statement qualifies as evidence.
Correct! This statement may be lighthearted, comparing invasives with schoolchildren who can’t “play well with others,” but the fact that invasives cause trouble and also multiply uncontrollably are important pieces of evidence in support of the claim.

b. No, this statement does not quality as evidence.
Try again.

4. We should kill and eat more invasives because “It’s as if you came home from work and a bunch of people had moved into your house.”

a. Yes, this statement qualifies as evidence.
Correct! This is part of the analogy comparing invasives with house-breaking strangers. It is logical evidence rather than factual evidence. By analogy, it makes the point that there is a good reason why invasives are not welcome.

b. No, this statement does not quality as evidence.
Try again.
