Given a paragraph and a claim, classify it this way: If the claim contradicts the evidence present in the paragraph, classify the claim as '0'. If the claim has multiple supporting *AND* contradicting evidences, classify the claim as '1'. If the claim has supporting evidence and the paragraph is in overall favor of the claim, then classify the claim as '2'.
One example is below.
Q: Paragraph: While the financial costs of screening mammography&!1-positive recalls&biopsies were not included in the study,readers would benefit from being reminded that recall mammography&biopsies increase patient financial costs.This article leads with valuable information for all women over age 40 by stating “Getting screening mammograms every two years instead of annually reduces the chance of a!1 alarm,a new study shows.” Unfortunately the writer doesn’t quantify or elaborate adequately on that reduction.Instead,the writer later focuses on how women undergoing screening mammography shouldn’t be anxious if they experience a recall because over half of women who have screening mammograms for 10 years will be recalled.Readers would have been better served if the writer had emphasized the significant reduction in both recall mammograms&!1-positive biopsies in women who are screened every two years rather than annually.Part of the continuing controversy over screening mammography focuses on annual versus biennial screening.Because this study showed a significant reduction in the percentage of those recalled&needing biopsies among women who are screened every other year,with no statistically significant increase in late-stage diagnosis of breast cancer,the article should have emphasized those important findings.The piece states that the researchers noted that “…!1 positive recalls may cause inconvenience&anxiety and biopsies can cause pain and scarring.” This article fails to include several important facts about the study.1)This is a prospective cohort study of women screened between 1994-2006.2)Most of the mammograms were film rather than digital.3)Few women underwent screening for the entire 10 year period.4)Screening mammography recall rates are influenced by the skill of the radiologists who read the mammograms.There was no disease mongering.No independent experts were quoted.The story did an adequate job comparing – at a very high level – annual screening versus biennial screening.Screening mammography is widely available throughout the United States.The study did not examine a new procedure.There’s no evidence that the story relied solely on a news release. 
Claim: Annual Mammograms May Have More False-Positives
A: 1
Rationale: This article reports on the results of a study of nearly 170,0 women who had screening mammograms beginning between age 40-59.The study found that over ten years of screening mammograms,over half of the women will experience a!1-positive recall for additional mammography.In addition,7%-9%of the women will have a biopsy for a suspicious lump which is not cancerous.Both of those percentages decrease if the woman is screened every other year rather than every year.Even with biennial mammography,41%of women will experience a recall over 10 years of mammography.The study’s Principal Investigator emphasized that “in most cases,a recall doesn’t mean you have cancer.” She hoped this knowledge would reduce the anxiety of women who are recalled.The story never explained the size of the decrease in the number of!1 positives between annual(61.3%) and biennial screening(41.6%).Our first two reviewers were a researcher who specializes in health decisions and a breast cancer survivor trained in evidence by the Natiional Breast Cancer Coalition’s Project LEAD.This study is valuable because it helps to quantify and compare the harms of annual and biennial screening,specifically the number of!1 positives and the number of unnecessary biopsies.Prior to this study,estimates of!1 positive screening mammography rates varied widely.The critical question is whether you can do less frequent screening,subject women to fewer harms and get similar results in terms of detection of “early stage” cancer.This study’s data seems to suggest that answer is yes.
Q: Paragraph: As the CostCo retail chain prepared to implement new requirements for shoppers, a message of support for the policy gained traction among Facebook users.The post is based around a photograph of a sign informing shoppers that members will be required to wear face coverings when shopping at CostCo warehouses starting on Monday, May 4 2020.“Members without face coverings will not be permitted inside the warehouse,” the sign reads:At least one iteration of the lengthy post, attributed to Cherrie Vierra Lonkar, has been shared nearly 1,000 times on the platform. She wrote:Ask yourself why you, a retail shopper deserve a handout from Costco. I mean you’ve eaten $5000 worth of free samples there in your lifetime anyway. ￼We are asking many of our healthcare workers to wear bandanas and t-shirts as masks. You aren’t above it. There are school children all over this country who are sewing masks to give away. If a 7 year old can be a decent person and choose to make the world a little more comfortable or safe, then so can you.This isn’t a Burger King drive-through, and no we can’t have it our way. This disease, infection, pandemic, whatever you wanna call it, doesn’t give a shit about you or me. Doesn’t give a shit about black, white, short, tall, age, gender. It’s not our battle to dictate￼.The bottom line is, don’t be a dick. Just put a mask on your self centered, mouth breathing face and let the greeter see the smile in our eyes as we head off to buy our cases of bottled water, pool floats, 10 pound bags of Cheetos, bulk items and cheap premixed margaritas. You’ll be fine.However another version, presented as an extended quote without attribution, has been shared more than 4,500 times since being posted on April 29, 2020.CostCo president Craig Jelinek confirmed the new rule in a letter to members posted on the company’s website, saying:Costco employees are required to wear face coverings, and now we are asking that Costco members do so too. We know some members may find this inconvenient or objectionable, but under the circumstances we believe the added safety is worth any inconvenience. This is not simply a matter of personal choice; a face covering protects not just the wearer, but others too.In short, we believe this is the right thing to do under the current circumstances. Although some may disagree with this policy or question its effectiveness, we’re choosing to err on the side of safety in our shopping environments. Costco has continued to operate during this crisis as an essential business in all of our communities, and our employees are on the front lines. As part of a community, we believe this simple act of safety and courtesy is one that Costco members and employees can undertake together.However, the requirement does not extend to children under the age of 2 or to anyone who cannot wear a mask or face covering for medical reasons.Several states and retail chains have shifted safety policies in response to the COVID-19 pandemic, with some opting to walk back laws banning the use of non-reusable shopping bags.Comments Claim: CostCo stores will require shoppers to wear masks beginning on May 4, 2020.
