Extract the answer to the question from the following context. Question: What is a characteristic of tense vowels? Context: Vowel length is not always considered a distinctive feature in Dutch phonology, because it normally co-occurs with changes in vowel quality. One feature or the other may be considered redundant, and some phonemic analyses prefer to treat it as an opposition of tenseness. However, even if not considered part of the phonemic opposition, the long/tense vowels are still realised as phonetically longer than their short counterparts. The changes in vowel quality are also not always the same in all dialects, and in some there may be little difference at all, with length remaining the primary distinguishing feature. And while it is true that older words always pair vowel length with a change in vowel quality, new loanwords have reintroduced phonemic oppositions of length. Compare zonne(n) [zn] ("suns") versus zone [zn] ("zone") versus zonen [zon(n)] ("sons"), or kroes [krus] ("mug") versus cruise [krus] ("cruise").

Extract the answer to the question from the following context. Question: What is the capacitor used for? Context: Finally, hysteresis synchronous motors typically are (essentially) two-phase motors with a phase-shifting capacitor for one phase. They start like induction motors, but when slip rate decreases sufficiently, the rotor (a smooth cylinder) becomes temporarily magnetized. Its distributed poles make it act like a PMSM. The rotor material, like that of a common nail, will stay magnetized, but can also be demagnetized with little difficulty. Once running, the rotor poles stay in place; they do not drift.

Answer: phase-shifting

Extract the answer to the question from the following context. Question: What was being argued against by the scholars? Context: However, the Orthodox claim to absolute fidelity to past tradition has been challenged by scholars who contend that the Judaism of the Middle Ages bore little resemblance to that practiced by today's Orthodox. Rather, the Orthodox community, as a counterreaction to the liberalism of the Haskalah movement, began to embrace far more stringent halachic practices than their predecessors, most notably in matters of Kashrut and Passover dietary laws, where the strictest possible interpretation becomes a religious requirement, even where the Talmud explicitly prefers a more lenient position, and even where a more lenient position was practiced by prior generations.
