Problem: ELPJ, a Japanese-based company, sells a laser turntable that uses a laser to read vinyl discs optically, without physical contact. The laser turntable eliminates record wear and the possibility of accidental scratches, which degrade the sound, but its expense limits use primarily to digital archiving of analog records, and the laser does not play back colored vinyl or picture discs. Various other laser-based turntables were tried during the 1990s, but while a laser reads the groove very accurately, since it does not touch the record, the dust that vinyl attracts due to static electric charge is not mechanically pushed out of the groove, worsening sound quality in casual use compared to conventional stylus playback.
What was a drawback of laser read discs?
The answer is the following: degrade the sound

Input: Article: A number of theories have been proposed regarding Avicenna's madhab (school of thought within Islamic jurisprudence). Medieval historian Ẓahīr al-dīn al-Bayhaqī (d. 1169) considered Avicenna to be a follower of the Brethren of Purity. On the other hand, Dimitri Gutas along with Aisha Khan and Jules J. Janssens demonstrated that Avicenna was a Sunni Hanafi. However, the 14th cenutry Shia faqih Nurullah Shushtari according to Seyyed Hossein Nasr, maintained that he was most likely a Twelver Shia. Conversely, Sharaf Khorasani, citing a rejection of an invitation of the Sunni Governor Sultan Mahmoud Ghazanavi by Avicenna to his court, believes that Avicenna was an Ismaili. Similar disagreements exist on the background of Avicenna's family, whereas some writers considered them Sunni, some more recent writers contested that they were Shia.

Now answer this question: Who thought that Avicenna was a Brethren of Purity follower?

Output: Medieval historian Ẓahīr al-dīn al-Bayhaqī


Article: In 1999, there was a double homicide in the Westside Clothing store on Lincoln Boulevard. During the incident, Culver City gang members David "Puppet" Robles and Jesse "Psycho" Garcia entered the store masked and began opening fire, killing Anthony and Michael Juarez. They then ran outside to a getaway vehicle driven by a third Culver City gang member, who is now also in custody. The clothing store was believed to be a local hang out for Santa Monica gang members. The dead included two men from Northern California who had merely been visiting the store's owner, their cousin, to see if they could open a similar store in their area. Police say the incident was in retaliation for a shooting committed by the Santa Monica 13 gang days before the Juarez brothers were gunned down.

Question: Where was this homicide perpetrated?
Ans: Westside Clothing store


Input: Estonian language
When Estonia was invaded and occupied by the Soviet Union in World War II, the status of the Estonian language changed to the first of two official languages (Russian being the other one). As with Latvia many immigrants entered Estonia under Soviet encouragement. In the second half of the 1970s, the pressure of bilingualism (for Estonians) intensified, resulting in widespread knowledge of Russian throughout the country. The Russian language was termed as ‘the language of friendship of nations’ and was taught to Estonian children, sometimes as early as in kindergarten. Although teaching Estonian to non-Estonians in schools was compulsory, in practice learning the language was often considered unnecessary.

Who invaded Estonia?
Output:
Soviet Union
