Question: Extract the answer to the question from the following context. Question: How do plants get carbon dioxide? Context: Plants uptake essential elements from the soil through their roots and from the air (consisting of mainly nitrogen and oxygen) through their leaves. Green plants obtain their carbohydrate supply from the carbon dioxide in the air by the process of photosynthesis. Carbon and oxygen are absorbed from the air, while other nutrients are absorbed from the soil. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps. These hydrogen ions displace cations attached to negatively charged soil particles so that the cations are available for uptake by the root. In the leaves, stomata open to take in carbon dioxide and expel oxygen. The carbon dioxide molecules are used as the carbon source in photosynthesis.
Answer: photosynthesis

Question: Extract the answer to the question from the following context. Question: What disease decreased hope for TB eradication? Context: Tuberculosis is the second-most common cause of death from infectious disease (after those due to HIV/AIDS). The total number of tuberculosis cases has been decreasing since 2005, while new cases have decreased since 2002. China has achieved particularly dramatic progress, with about an 80% reduction in its TB mortality rate between 1990 and 2010. The number of new cases has declined by 17% between 2004–2014. Tuberculosis is more common in developing countries; about 80% of the population in many Asian and African countries test positive in tuberculin tests, while only 5–10% of the US population test positive. Hopes of totally controlling the disease have been dramatically dampened because of a number of factors, including the difficulty of developing an effective vaccine, the expensive and time-consuming diagnostic process, the necessity of many months of treatment, the increase in HIV-associated tuberculosis, and the emergence of drug-resistant cases in the 1980s.
Answer: HIV

Question: Extract the answer to the question from the following context. Question: What group of people lauded Burke's book, but overlooked its genre? Context: Burke claimed that Bolingbroke's arguments against revealed religion could apply to all social and civil institutions as well. Lord Chesterfield and Bishop Warburton (and others) initially thought that the work was genuinely by Bolingbroke rather than a satire. All the reviews of the work were positive, with critics especially appreciative of Burke's quality of writing. Some reviewers failed to notice the ironic nature of the book, which led to Burke stating in the preface to the second edition (1757) that it was a satire.
Answer:
Some reviewers
