Problem: Wang and Nyima state that after the official title "Education Minister" was granted to Tai Situ Changchub Gyaltsen (13021364) by the Yuan court, this title appeared frequently with his name in various Tibetan texts, while his Tibetan title "Degsi" (sic properly sde-srid or desi) is seldom mentioned. Wang and Nyima take this to mean that "even in the later period of the Yuan dynasty, the Yuan imperial court and the Phagmodrupa Dynasty maintained a Central-local government relation." The Tai Situpa is even supposed to have written in his will: "In the past I received loving care from the emperor in the east. If the emperor continues to care for us, please follow his edicts and the imperial envoy should be well received."
What Tibetan title was hardly ever mentioned when referring to Tai Situ Changchub Gyaltsen?

Answer: Degsi

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Much of the study in the madrasah college centred on examining whether certain opinions of law were orthodox. This scholarly process of "determining orthodoxy began with a question which the Muslim layman, called in that capacity mustafti, presented to a jurisconsult, called mufti, soliciting from him a response, called fatwa, a legal opinion (the religious law of Islam covers civil as well as religious matters). The mufti (professor of legal opinions) took this question, studied it, researched it intensively in the sacred scriptures, in order to find a solution to it. This process of scholarly research was called ijtihad, literally, the exertion of one's efforts to the utmost limit."
What is ijtihad?
A: process of scholarly research

Is there an answer to this question: What other type of architecture also made use of the curved arch?

Answer: unanswerable

Question: Matte solder is usually fused to provide a better bonding surface or stripped to bare copper. Treatments, such as benzimidazolethiol, prevent surface oxidation of bare copper. The places to which components will be mounted are typically plated, because untreated bare copper oxidizes quickly, and therefore is not readily solderable. Traditionally, any exposed copper was coated with solder by hot air solder levelling (HASL). The HASL finish prevents oxidation from the underlying copper, thereby guaranteeing a solderable surface. This solder was a tin-lead alloy, however new solder compounds are now used to achieve compliance with the RoHS directive in the EU and US, which restricts the use of lead. One of these lead-free compounds is SN100CL, made up of 99.3% tin, 0.7% copper, 0.05% nickel, and a nominal of 60ppm germanium.
Is there an answer to this question: What is now used in compliance with the RoHS directive in the EU and China?

unanswerable
