Input: Read this: Asthma is thought to be caused by a combination of genetic and environmental factors. Environmental factors include exposure to air pollution and allergens. Other potential triggers include medications such as aspirin and beta blockers. Diagnosis is usually based on the pattern of symptoms, response to therapy over time, and spirometry. Asthma is classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate. It may also be classified as atopic or non-atopic where atopy refers to a predisposition toward developing a type 1 hypersensitivity reaction.
Question: What two categories can spirometry also be classified into?

Output: unanswerable

Input: Read this: In Eastern Buddhism, there is also a distinctive Vinaya and ethics contained within the Mahayana Brahmajala Sutra (not to be confused with the Pali text of that name) for Bodhisattvas, where, for example, the eating of meat is frowned upon and vegetarianism is actively encouraged (see vegetarianism in Buddhism). In Japan, this has almost completely displaced the monastic vinaya, and allows clergy to marry.
Question: Distinctive Vinaya and ethics are contained within what sutra?

Output: Mahayana Brahmajala

Input: Read this: Treatment of TB uses antibiotics to kill the bacteria. Effective TB treatment is difficult, due to the unusual structure and chemical composition of the mycobacterial cell wall, which hinders the entry of drugs and makes many antibiotics ineffective. The two antibiotics most commonly used are isoniazid and rifampicin, and treatments can be prolonged, taking several months. Latent TB treatment usually employs a single antibiotic, while active TB disease is best treated with combinations of several antibiotics to reduce the risk of the bacteria developing antibiotic resistance. People with latent infections are also treated to prevent them from progressing to active TB disease later in life. Directly observed therapy, i.e., having a health care provider watch the person take their medications, is recommended by the WHO in an effort to reduce the number of people not appropriately taking antibiotics. The evidence to support this practice over people simply taking their medications independently is poor. Methods to remind people of the importance of treatment do, however, appear effective.
Question: What health care provider watches the person take their medications?

Output: unanswerable
