Problem: Antibiotics:

Antibiotics are screened for any negative effects on humans or other mammals before approval for clinical use, and are usually considered safe and most are well tolerated. However, some antibiotics have been associated with a range of adverse side effects. Side-effects range from mild to very serious depending on the antibiotics used, the microbial organisms targeted, and the individual patient. Side effects may reflect the pharmacological or toxicological properties of the antibiotic or may involve hypersensitivity reactions or anaphylaxis. Safety profiles of newer drugs are often not as well established as for those that have a long history of use. Adverse effects range from fever and nausea to major allergic reactions, including photodermatitis and anaphylaxis. Common side-effects include diarrhea, resulting from disruption of the species composition in the intestinal flora, resulting, for example, in overgrowth of pathogenic bacteria, such as Clostridium difficile. Antibacterials can also affect the vaginal flora, and may lead to overgrowth of yeast species of the genus Candida in the vulvo-vaginal area. Additional side-effects can result from interaction with other drugs, such as elevated risk of tendon damage from administration of a quinolone antibiotic with a systemic corticosteroid. Some scientists have hypothesized that the indiscriminate use of antibiotics alter the host microbiota and this has been associated with chronic disease.

What causes diarrhea?

A: disruption of the species composition in the intestinal flora


Problem: Structural material that resembles ordinary, "dicot" or conifer wood in its gross handling characteristics is produced by a number of monocot plants, and these also are colloquially called wood. Of these, bamboo, botanically a member of the grass family, has considerable economic importance, larger culms being widely used as a building and construction material in their own right and, these days, in the manufacture of engineered flooring, panels and veneer. Another major plant group that produce material that often is called wood are the palms. Of much less importance are plants such as Pandanus, Dracaena and Cordyline. With all this material, the structure and composition of the structural material is quite different from ordinary wood.
What's another term used for "conifer" wood?
---
Answer: dicot


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
There is disagreement whether madaris ever became universities. Scholars like Arnold H. Green and Seyyed Hossein Nasr have argued that starting in the 10th century, some medieval Islamic madaris indeed became universities. George Makdisi and others, however, argue that the European university has no parallel in the medieval Islamic world. Darleen Pryds questions this view, pointing out that madaris and European universities in the Mediterranean region shared similar foundations by princely patrons and were intended to provide loyal administrators to further the rulers' agenda. Other scholars regard the university as uniquely European in origin and characteristics.
Who agreed that European universities and Islamic madaris have very little in common?
A: unanswerable


Context and question: Software developers can't test everything, but they can use combinatorial test design to identify the minimum number of tests needed to get the coverage they want. Combinatorial test design enables users to get greater test coverage with fewer tests. Whether they are looking for speed or test depth, they can use combinatorial test design methods to build structured variation into their test cases. Note that "coverage", as used here, is referring to combinatorial coverage, not requirements coverage.
Although software developers are unable to test everything, what do they run to keep the testing to a minimum? 
Answer: use combinatorial test design


Question: According to the latest nationwide census, Roman Catholics constituted 30.8% of the total population of Germany, followed by the Evangelical Protestants at 30.3%. Other religions, atheists or not specified constituted 38.8% of the population at the time. Among "others" are Protestants not included in Evangelical Church of Germany, and other Christians such as the Restorationist New Apostolic Church. Protestantism was more common among the citizens of Germany. The North and East Germany is predominantly Protestant, the South and West rather Catholic. Nowadays there is a non-religious majority in Hamburg and the East German states.
Is there an answer to this question: What percentage of Germans are Roman Catholic?

Answer: 30.8


QUES: An additional 4.6 billion tonnes of uranium are estimated to be in sea water (Japanese scientists in the 1980s showed that extraction of uranium from sea water using ion exchangers was technically feasible). There have been experiments to extract uranium from sea water, but the yield has been low due to the carbonate present in the water. In 2012, ORNL researchers announced the successful development of a new absorbent material dubbed HiCap which performs surface retention of solid or gas molecules, atoms or ions and also effectively removes toxic metals from water, according to results verified by researchers at Pacific Northwest National Laboratory.

What did ORNL call their material that performs surface retention on solid molecules?
What is the answer?
ANS:
HiCap
