Input: Read this: Using histological stains on expectorated samples from phlegm (also called "sputum"), scientists can identify MTB under a microscope. Since MTB retains certain stains even after being treated with acidic solution, it is classified as an acid-fast bacillus. The most common acid-fast staining techniques are the Ziehl–Neelsen stain and the Kinyoun stain, which dye acid-fast bacilli a bright red that stands out against a blue background. Auramine-rhodamine staining and fluorescence microscopy are also used.
Question: What become blue when stained?

Output: unanswerable


Input: Read this: Relations between Ashkenazim and Sephardim have not always been warm. North African Sepharadim and Berber Jews were often looked upon by Ashkenazim as second-class citizens during the first decade after the creation of Israel. This has led to protest movements such as the Israeli Black Panthers led by Saadia Marciano a Moroccan Jew. Nowadays, relations are getting better. In some instances, Ashkenazi communities have accepted significant numbers of Sephardi newcomers, sometimes resulting in intermarriage.
Question: Who led the Israeli Black Panthers?

Output: Saadia Marciano

Input: Read this: "Green" in modern European languages corresponds to about 520–570 nm, but many historical and non-European languages make other choices, e.g. using a term for the range of ca. 450–530 nm ("blue/green") and another for ca. 530–590 nm ("green/yellow").[citation needed] In the comparative study of color terms in the world's languages, green is only found as a separate category in languages with the fully developed range of six colors (white, black, red, green, yellow, and blue), or more rarely in systems with five colors (white, red, yellow, green, and black/blue). (See distinction of green from blue) These languages have introduced supplementary vocabulary to denote "green", but these terms are recognizable as recent adoptions that are not in origin color terms (much like the English adjective orange being in origin not a color term but the name of a fruit). Thus, the Thai word เขียว besides meaning "green" also means "rank" and "smelly" and holds other unpleasant associations.
Question: In which language does the word for "green" also mean "rank" and "smelly"?

Output:
Thai
