Problem: Given the question: Extract the answer to the question from the following context. Question: What had a positive effect on the lifestyle of the gentry? Context: As some szlachta were poorer than some non-noble gentry, some particularly impoverished szlachta were forced to become tenants of the wealthier gentry. In doing so, however, these szlachta retained all their constitutional prerogatives, as it was not wealth or lifestyle (obtainable by the gentry), but hereditary juridical status, that determined nobility.

wealth

Problem: Given the question: Extract the answer to the question from the following context. Question: Yue is dated earliest back to what time known by seasons? Context: The area of modern Zhejiang was outside the major sphere of influence of the Shang civilization during the second millennium BC. Instead, this area was populated by peoples collectively known as the Hundred Yue, including the Dongyue and the Ouyue. The kingdom of Yue began to appear in the chronicles and records written during the Spring and Autumn Period. According to the chronicles, the kingdom of Yue was located in northern Zhejiang. Shiji claims that its leaders were descended from the Shang founder Yu the Great. Evidence suggests that Baiyue and the kingdom of Yue possessed their own culture and history that are different from those kingdoms in north and central China, whose cultures and histories were carefully recorded in chronicles and histories during the Spring and Autumn Period and into the Qin dynasty. The Song of the Yue Boatman (Chinese: , p Yueren Ge, lit. "Song of the man of Yue") was transliterated into Chinese and recorded by authors in north China or inland China of Hebei and Henan around 528 BC. The song shows that the Yue people spoke a language that was mutually unintelligible with the dialects spoken in north and inland China. The Yue peoples seem to have had their own written script. The Sword of Goujian bears bird-worm seal script. Yuenu (Chinese: ; pinyin: Yuenu; WadeGiles: Yueh-nu; literally: "the Lady of Yue") was a swordswoman from the state of Yue. In order to check the growth of the kingdom of Wu, Chu pursued a policy of strengthening Yue. Under King Goujian, Yue recovered from its early reverses and fully annexed the lands of its rival in 473 BC. The Yue kings then moved their capital center from their original home around Mount Kuaiji in present-day Shaoxing to the former Wu capital at present-day Suzhou. With no southern power to turn against Yue, Chu opposed it directly and, in 333 BC, succeeded in destroying it. Yue's former lands were annexed by the Qin Empire in 222 BC and organized into a commandery named for Kuaiji in Zhejiang but initially headquartered in Wu in Jiangsu.

Problem: Given the question: Extract the answer to the question from the following context. Question: What does the rotor field communicate with? Context: A PM motor does not have a field winding on the stator frame, instead relying on PMs to provide the magnetic field against which the rotor field interacts to produce torque. Compensating windings in series with the armature may be used on large motors to improve commutation under load. Because this field is fixed, it cannot be adjusted for speed control. PM fields (stators) are convenient in miniature motors to eliminate the power consumption of the field winding. Most larger DC motors are of the "dynamo" type, which have stator windings. Historically, PMs could not be made to retain high flux if they were disassembled; field windings were more practical to obtain the needed amount of flux. However, large PMs are costly, as well as dangerous and difficult to assemble; this favors wound fields for large machines.
