Problem: Asthma:

As of 2011, 235–330 million people worldwide are affected by asthma, and approximately 250,000–345,000 people die per year from the disease. Rates vary between countries with prevalences between 1 and 18%. It is more common in developed than developing countries. One thus sees lower rates in Asia, Eastern Europe and Africa. Within developed countries it is more common in those who are economically disadvantaged while in contrast in developing countries it is more common in the affluent. The reason for these differences is not well known. Low and middle income countries make up more than 80% of the mortality.

What countries is asthma more commonly seen?
---
A: It is more common in developed than developing countries


Problem: The majority of studies indicate antibiotics do interfere with contraceptive pills, such as clinical studies that suggest the failure rate of contraceptive pills caused by antibiotics is very low (about 1%). In cases where antibacterials have been suggested to affect the efficiency of birth control pills, such as for the broad-spectrum antibacterial rifampicin, these cases may be due to an increase in the activities of hepatic liver enzymes' causing increased breakdown of the pill's active ingredients. Effects on the intestinal flora, which might result in reduced absorption of estrogens in the colon, have also been suggested, but such suggestions have been inconclusive and controversial. Clinicians have recommended that extra contraceptive measures be applied during therapies using antibacterials that are suspected to interact with oral contraceptives.
In therapy, what does the antibacterial interact with?
---
Answer: oral contraceptives


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
There has been some concern over the potential adverse environmental and ecosystem effects caused by the influx of visitors. Some environmentalists and scientists have made a call for stricter regulations for ships and a tourism quota. The primary response by Antarctic Treaty Parties has been to develop, through their Committee for Environmental Protection and in partnership with IAATO, "site use guidelines" setting landing limits and closed or restricted zones on the more frequently visited sites. Antarctic sightseeing flights (which did not land) operated out of Australia and New Zealand until the fatal crash of Air New Zealand Flight 901 in 1979 on Mount Erebus, which killed all 257 aboard. Qantas resumed commercial overflights to Antarctica from Australia in the mid-1990s.
Where did sightseeing flights that did land operate out of?
A: unanswerable

Question: Holy Cross Father John Francis O'Hara was elected vice-president in 1933 and president of Notre Dame in 1934. During his tenure at Notre Dame, he brought numerous refugee intellectuals to campus; he selected Frank H. Spearman, Jeremiah D. M. Ford, Irvin Abell, and Josephine Brownson for the Laetare Medal, instituted in 1883. O'Hara strongly believed that the Fighting Irish football team could be an effective means to "acquaint the public with the ideals that dominate" Notre Dame. He wrote, "Notre Dame football is a spiritual service because it is played for the honor and glory of God and of his Blessed Mother. When St. Paul said: 'Whether you eat or drink, or whatsoever else you do, do all for the glory of God,' he included football."
Is there an answer to this question: Irvin Abell was given what award by Notre Dame?

Answer: Laetare Medal
