Teacher: 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'.
Teacher: Now, understand the problem? If you are still confused, see the following example:
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
Solution: 1
Reason: 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.

Now, solve this instance: Paragraph: Extinction Rebellion, which uses civil disobedience to highlight the risks posed by climate change and the accelerating loss of plant and animal species, is midway through a new two-week wave of actions in cities around the world. Activists thronged the financial heart of London on Monday, unfurling banners, addressing passersby by megaphone or blocking streets around locations including BlackRock, the Bank of England, Bank of China and Barclays. At BlackRock, volunteers glued themselves to the doors while others staged a mock dinner party with rolled-up banknotes on their plates. Police said they arrested more than 90 people. The arrestees included Rabbi Jeffrey Newman of the Finchley Reform Synagogue, who was arrested near the Bank of England praying, singing and wearing a prayer shawl for the first day of the Jewish festival Sukkot, Extinction Rebellion said. “The City of London is a preeminent nexus of power in the global system that is killing our world,” said Carolina Rosa, spokesperson for Extinction Rebellion. BlackRock declined to comment. Police later ordered a halt to all assembly linked to   Extinction Rebellion in London. At Trafalgar Square in the heart of the city, where demonstrators have pitched camp for the past week amid fountains at the base of Nelson’s Column, protesters began removing tents. Police made no immediate move to shut down another main protest camp in the district of Vauxhall. “Officers have begun the process of clearing Trafalgar Square and getting things back to normal,” said Deputy Assistant Commissioner Laurence Taylor. Extinction Rebellion said it had left Trafalgar Square but would continue actions in London and cities around the world. “The Climate and Ecological Emergency isn’t going away and we remain resolute in facing it. We urge the Government and the authorities to join us in doing the same,” the group said in a statement. “This is bigger than all of us.”   Extinction Rebellion wants to cause enough disruption to force governments to rapidly cut carbon emissions and reverse the collapse of ecosystems to avert the worst of the devastation scientists project if business as usual continues. Critics say the group is proposing what amounts to the overthrow of capitalism without any clear idea of what would follow, and that the world needs fossil fuels. Extinction Rebellion said that more than 1,400 people had been arrested in London since it launched its latest actions a week ago. A similar number has in total been arrested in 20 cities in countries including the Netherlands, Belgium, the United States, Australia, Canada and New Zealand. While activists have long targeted fossil fuel companies, a growing global climate protest movement is increasingly scrutinizing the role fund managers, banks and insurance companies play in enabling oil and gas extraction. Emily Grossman, a British science broadcaster who has a PhD in molecular biology, who joined the protest outside BlackRock, said that financing fossil fuel projects was undermining the goals of the 2015 Paris Agreement to limit global warming. “This is criminal damage that they are doing to our lives and to the lives of our children and it has to stop,” said Grossman, who was later led away by police. Major oil companies have approved $50 billion of projects since last year that run contrary to the goals of the Paris Agreement, according to an analysis published last month by financial think-tank Carbon Tracker. Fossil fuel companies say they need to invest in new projects to meet future demand for energy, particularly in fast-growing regions such as Asia. Climate protesters want to pressure index fund firms such as BlackRock because the sector, which now controls half the U.S. stock mutual fund market, has enormous power to influence companies in which they invest trillions of dollars. The leading U.S. index fund firms, BlackRock, Vanguard Group and State Street Corp, rarely use that clout, a Reuters analysis of their shareholder-voting records found this month. Claim: John Faso took money from fossil fuel companies as they tried to take your land by eminent domain for a fracked gas pipeline.
