III. Contextual Matching (8%)        Are some people resistant to COVID-19? After dodging COVID-19 several times during thepandemic, flight attendant Angeliki Kaoukaki wondered if she was a medical 23 . But she’spossibly among a small group of people who might have genetic resistance to the virus. Scientistsare now racing to understand how such resistance to COVID-19 could work—and whether the traitcan be __24__ to develop new drugs against the disease.        Kaoukaki had already worked alongside other cabin crew members who tested positivewithout getting sick herself. Then in July 2021 Kaoukaki’s partner __25__ a severe case ofCOVID-19 with high fever and unbearable pain that lasted nearly 10 days. Kaoukaki showed nosymptoms, despite the fact that the pair isolated together for two weeks in their studio apartment inAthens, Greece.        She continued to test negative on multiple PCR and rapid antigen tests, and a test she took 23days after her partner’s confirmed infection __26__ no antibodies in her blood.        “Every day I heard [from doctors] that maybe you have COVID,” she says, “but again andagain, I tested negative.”        Despite both being vaccinated, her partner got COVID-19 again during the Omicron wave inJanuary. Kaoukaki isolated with him for five days and again showed no symptoms and continued totest negative for the virus. That’s when she began to __27__ an explanation.        An online article led her to Evangelos Andreakos, an immunologist at the Biomedical ResearchFoundation of the Academy of Athens. He is part of an international __28__ called the COVIDHuman Genetic Effort that has been looking for genetic variations that might reveal why somepeople never get COVID-19.      Although Andreakos and his colleagues didn’t expect to find many such individuals for theirstudy, they were overwhelmed with emails from at least 5,000 volunteers worldwide with storiessimilar to Kaoukaki’s. Using saliva samples from the 20 percent of people who met their studycriteria, Andreakos and his team will be scanning the protein-coding regions of genes in their DNAto spot any __29__ that may be absent in the genetic sequences from patients who had severe ormoderate cases of COVID-19. The hope is that some of these people__30__ the secret toCOVID-19 resistance.     “We expect it to be a rare population,” Andreakos says. “But there are precedents.” (AB) anomaly (AC) consortium (AD) contracted (AE) harbor (BC) harnessed (BD) hunt for (BE) mutations (CD) subject (CE) suggested (DE) put forward
