The problem: Answer a question about this article:
New or "virgin" heavy/heavyweight (180–220 g) vinyl is commonly used for modern audiophile vinyl releases in all genres. Many collectors prefer to have heavyweight vinyl albums, which have been reported to have better sound than normal vinyl because of their higher tolerance against deformation caused by normal play. 180 g vinyl is more expensive to produce only because it uses more vinyl. Manufacturing processes are identical regardless of weight. In fact, pressing lightweight records requires more care. An exception is the propensity of 200 g pressings to be slightly more prone to non-fill, when the vinyl biscuit does not sufficiently fill a deep groove during pressing (percussion or vocal amplitude changes are the usual locations of these artifacts). This flaw causes a grinding or scratching sound at the non-fill point.
Would would a non filled area in a vinyl press cause when listening to a record?
****
The answer: grinding or scratching sound


The problem: Answer a question about this article:
It was temporarily under the control of the Tibetan empire and Chinese from 650–680 and then under the control of the Umayyads in 710. The Samanid Empire, 819 to 999, restored Persian control of the region and enlarged the cities of Samarkand and Bukhara (both cities are today part of Uzbekistan) which became the cultural centers of Iran and the region was known as Khorasan. The Kara-Khanid Khanate conquered Transoxania (which corresponds approximately with modern-day Uzbekistan, Tajikistan, southern Kyrgyzstan and southwest Kazakhstan) and ruled between 999–1211. Their arrival in Transoxania signaled a definitive shift from Iranian to Turkic predominance in Central Asia, but gradually the Kara-khanids became assimilated into the Perso-Arab Muslim culture of the region.
When was the region under Tibetan empire and the CHinese?
****
The answer: 650–680

In October 2009, the American Law Institute voted to disavow the framework for capital punishment that it had created in 1962, as part of the Model Penal Code, "in light of the current intractable institutional and structural obstacles to ensuring a minimally adequate system for administering capital punishment." A study commissioned by the institute had said that experience had proved that the goal of individualized decisions about who should be executed and the goal of systemic fairness for minorities and others could not be reconciled.
What goal did the ALI's study say could not be reconciled with the goal of individualized execution decisions?
****
The answer: systemic fairness for minorities
