Problem: Hokkien:

In general, Hokkien dialects have 5 to 7 phonemic tones. According to the traditional Chinese system, however, there are 7 to 9 "tones",[citation needed] more correctly termed tone classes since two of them are non-phonemic "entering tones" (see the discussion on Chinese tone). Tone sandhi is extensive. There are minor variations between the Quanzhou and Zhangzhou tone systems. Taiwanese tones follow the patterns of Amoy or Quanzhou, depending on the area of Taiwan. Many dialects have an additional phonemic tone ("tone 9" according to the traditional reckoning), used only in special or foreign loan words.

What dialects has less than 5 phonemic tones?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
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.
Why are antibiotics checked before use?
A: negative effects on humans or other mammals


Context and question: The film library of Turner Entertainment would serve as the base form of programming for TCM upon the network's launch. Before the creation of Turner Classic Movies, films from Turner's library of movies aired on the Turner Broadcasting System's advertiser-supported cable network TNT – along with colorized versions of black-and-white classics such as The Maltese Falcon. After the library was acquired, MGM/UA signed a deal with Turner to continue distributing the pre-May 1986 MGM and to begin distributing the pre-1950 Warner Bros. film libraries for video release (the rest of the library went to Turner Home Entertainment).
Who did Turner ink a deal with to distribute Warner Bros. films from before 1950?
Answer: MGM/UA


Question: Alloys of primarily zinc with small amounts of copper, aluminium, and magnesium are useful in die casting as well as spin casting, especially in the automotive, electrical, and hardware industries. These alloys are marketed under the name Zamak. An example of this is zinc aluminium. The low melting point together with the low viscosity of the alloy makes the production of small and intricate shapes possible. The low working temperature leads to rapid cooling of the cast products and therefore fast assembly is possible. Another alloy, marketed under the brand name Prestal, contains 78% zinc and 22% aluminium and is reported to be nearly as strong as steel but as malleable as plastic. This superplasticity of the alloy allows it to be molded using die casts made of ceramics and cement.
Is there an answer to this question: What are alloys of zinc mixed with copper, aluminium and plastic used for?

Answer: unanswerable


Problem: Software testing:

There are generally four recognized levels of tests: unit testing, integration testing, component interface testing, and system testing. Tests are frequently grouped by where they are added in the software development process, or by the level of specificity of the test. The main levels during the development process as defined by the SWEBOK guide are unit-, integration-, and system testing that are distinguished by the test target without implying a specific process model. Other test levels are classified by the testing objective.

What is classified by the pretesting objective?
