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'.

Paragraph: On 18 March 2016, an image of an opossum was uploaded to Imgur with overlaid text reading as follows:  Given the frequently absurd nature of “amazing facts” memes, many viewers were rightly skeptical of the claim attached to that photograph. The image provided no citations to substantiate the information it presented, and the notion that opossums were a possible tool in the epidemiological battle against Lyme disease seemed implausible to some. As it turned out, there is at least some truth to the opossum-as-tick-slayer rumors. On 18 April 2014, the Cary Institute of Ecosystem Studies and NewsTimes published an article that focused on the role of opossums in the spread of Lyme disease with respect to their role in the ecosystem: [N]ow ecologists have learned something else about opossums. They’re a sort of magnet when it comes to riding the world of black-legged ticks, which spread Lyme disease. “Don’t hit opossums if they’ve playing dead in the road,” said Richard Ostfeld, of the Cary Institute for Ecosystem Studies in Millbrook, N.Y. Ostfeld is forest ecologist and an expert on the environmental elements of infectious diseases like Lyme disease. Several years ago, scientists … tested six species — white-footed mice, chipmunks, squirrels, opossums and veerys and catbirds — by capturing and caging them, and then exposing each test subject to 100 ticks … [O]f the six, the opossums were remarkably good at getting rid of the ticks — much more so that any of the others. [A]mong other opossum traits, there is this: They groom themselves fastidiously, like cats. If they find a tick, they lick it off and swallow it … Extrapolating from their findings, Ostfeld said, the team estimated that in one season, an opossum can kill about 5,000 ticks … Some ticks end up getting their blood meal from the possum. But more than 90 percent of them ended up being groomed away and swallowed. “They’re net destroyers of ticks,” Ostfeld said. Ostfeld had previously discouraged disruption of opossum populations for this reason. In July 2012, he said in a podcast: Because many ticks try to feed on opossums and few of them survive the experience. Opossums are extraordinarily good groomers it turns out — we never would have thought that ahead of time — but they kill the vast majority — more than 95% percent of the ticks that try to feed on them. So these opossums are walking around the forest floor, hoovering up ticks right and left, killing over 90% of these things, and so they are really protecting our health. Ostfeld was also named as one author of a September 2009 study in Proceedings of the Royal Society which examined animal kingdom hosts “as ecological traps for the vector of Lyme disease” and asserted that: By subjecting field-caught hosts to parasitism by larval blacklegged ticks, we found that some host species (e.g. opossums, squirrels) that are abundantly parasitized in nature kill 83–96% of the ticks that attempt to attach and feed, while other species are more permissive of tick feeding. [T]he vast majority (96.5%) of larval ticks that encounter an opossum and attempt to feed are apparently consumed. Working backwards, [we calculate that] during any given week in the larval activity peak, each opossum must host more than 5500 larval ticks to produce 199 that successfully feed. By this logic, during the larval peak, each mouse encounters approximately 50 larval ticks per week, almost half of which feed to repletion and become nymphs. As far as “amazing facts” images go, the opossum/Lyme disease one was very well researched, with numbers that matched up with what ecologists have learned about opossums, deer ticks, and the spread of Lyme disease in recent years (although those studies surmised opossums kill approximately 5,000 ticks per season, not per week). Claim: Opossums kill thousands of ticks each week, inhibiting the spread of Lyme Disease to humans.

Paragraph: The Alpine republic with a population of 8.8 million has tested around 28,400 people so far with nearly 4,900 cases and 28 deaths confirmed. It was one of the first European countries to put severe restrictions on movement and close shops and schools in response to the developments in neighboring Italy and a strong increase in coronavirus infections in its western regions. In coming weeks, Austria plans to test up to 15,000 people per day, the chancellor said. “We will also launch rapid tests, to test hundreds of thousands of people, as quickly as possible,” Kurz told a news conference. He referred to brand new tests that are comparably cheap but take longer than laboratory tests used up until now. Broad testing is key to getting a clear picture of the real infection rate and an idea of how many people have developed immunity against the virus, the chancellor said. Top priority was to delay the peak of infections as long as possible to avoid a situation like in Italy or Spain, where the health systems are overwhelmed. “Our goal is that the number of infections doubles only every 14 days and not every two, three or five days and that we will set the right measures to keep it that way once we ramp up social life again,” Kurz said. Austria’s strict measures are in place until April 13, and Kurz said there was hope that a gradual withdrawal could start the day after. A government task force developing scenarios for the “ramp up” was currently dealing with questions such as in which order schools, businesses and production should restart. Lessons from other countries showed that it was crucial to remain disciplined and to make use of “big data”. Asked what he meant by “big data”, Kurz said: “We are currently working with the Red Cross and other enterprises on ideas that could be implemented in Austria and in Europe, and which are suitable for our system and our democracy.”   Austria’s Red Cross is promoting a so-called “Stop Corona” app, which enables a user to digitally store who he meets and when. If a person shows symptoms of corona disease, these contact persons can be notified. Austria’s mobile carrier A1 Telekom Austria  is already sharing results from a motion analysis application that visualizes the movement flows of groups of people with the health authority. Claim: Austria bets on mass testing to manage coronavirus spread.

Paragraph: The radiologists used angiography, an X-ray of the blood  vessels, to confirm loss of blood flow in the severely  frostbitten hands and feet of 17 patients. They threaded catheters into the arteries to directly  deliver clot-busting drugs to dissolve the blood clots and  anti-spasmodics to relax the arteries. This helped 90 percent of the patients, they told a meeting  in Washington of the Society of Interventional Radiology. “Previously, severe frostbite was a one-way route to limb  loss. This treatment is a significant improvement.” said Dr.  George Edmonson, an interventional radiologist with St. Paul  Radiology in St. Paul, Minnesota, who worked on the study. “We’re opening arteries that are blocked so that tissues  can heal and limbs can be salvaged. We were able to reopen even  the smallest arteries, saving patients’ fingers and toes,”  Edmonson added. Severe frostbite can block blood flow and cause small clots  to form. These clots can worsen already slowed blood flow. “For half our patients who received the clot-busting drug  Tenectaplase, this technique worked beautifully, saving all  fingers, hands, toes and feet that otherwise would have been  lost,” said Edmonson. “Overall, in about 80 percent of the cases, it  significantly improved patients’ outcomes. Within one to three  days of treatment, we saw improvement.” Claim: Clot-busting drugs save limbs from frostbite.
