Problem: Szlachta:

Today the word szlachta in the Polish language simply translates to "nobility". In its broadest meaning, it can also denote some non-hereditary honorary knighthoods granted today by some European monarchs. Occasionally, 19th-century non-noble landowners were referred to as szlachta by courtesy or error, when they owned manorial estates though they were not noble by birth. In the narrow sense, szlachta denotes the old-Commonwealth nobility.

Why were the non nobles and nobles referred as the same term?

A: by courtesy or error

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Spinal cord fibers dedicated to carrying A-delta fiber pain signals, and others that carry both A-delta and C fiber pain signals up the spinal cord to the thalamus in the brain have been identified. Other spinal cord fibers, known as wide dynamic range neurons, respond to A-delta and C fibers, but also to the large A-beta fibers that carry touch, pressure and vibration signals. Pain-related activity in the thalamus spreads to the insular cortex (thought to embody, among other things, the feeling that distinguishes pain from other homeostatic emotions such as itch and nausea) and anterior cingulate cortex (thought to embody, among other things, the motivational element of pain); and pain that is distinctly located also activates the primary and secondary somatosensory cortices. Melzack and Casey's 1968 picture of the dimensions of pain is as influential today as ever, firmly framing theory and guiding research in the functional neuroanatomy and psychology of pain.
Where do pain signals travel up to from the thalamus?
A: unanswerable

Context and question: The German materialist and atheist anthropologist Ludwig Feuerbach would signal a new turn in materialism through his book, The Essence of Christianity (1841), which provided a humanist account of religion as the outward projection of man's inward nature. Feuerbach's materialism would later heavily influence Karl Marx.
Who wrote "The Essence of Christianity"?
Answer: Ludwig Feuerbach

Question: Nevertheless, the Fujiwara were not demoted by Daigo but actually became stronger during his reign. Central control of Japan had continued to decline, and the Fujiwara, along with other great families and religious foundations, acquired ever larger shoen and greater wealth during the early tenth century. By the early Heian period, the shoen had obtained legal status, and the large religious establishments sought clear titles in perpetuity, waiver of taxes, and immunity from government inspection of the shoen they held. Those people who worked the land found it advantageous to transfer title to shoen holders in return for a share of the harvest. People and lands were increasingly beyond central control and taxation, a de facto return to conditions before the Taika Reform.
Is there an answer to this question: Where was central control growing?

Answer: unanswerable

In 680 Ibn al-Zubayr fled Medina for Mecca. Hearing about Husayn's opposition to Yazid I, the people of Kufa sent to Husayn asking him to take over with their support. Al-Husayn sent his cousin Muslim bin Agail to verify if they would rally behind him. When the news reached Yazid I, he sent Ubayd-Allah bin Ziyad, ruler of Basrah, with the instruction to prevent the people of Kufa rallying behind Al-Husayn. Ubayd-Allah bin Ziyad managed to disperse the crowd that gathered around Muslim bin Agail and captured him. Realizing Ubayd-Allah bin Ziyad had been instructed to prevent Husayn from establishing support in Kufa, Muslim bin Agail requested a message to be sent to Husayn to prevent his immigration to Kufa. The request was denied and Ubayd-Allah bin Ziyad killed Muslim bin Agail. While Ibn al-Zubayr would stay in Mecca until his death, Husayn decided to travel on to Kufa with his family, unaware of the lack of support there. Husayn and his family were intercepted by Yazid I's forces led by Amru bin Saad, Shamar bin Thi Al-Joshan, and Hussain bin Tamim, who fought Al-Husayn and his male family members until they were killed. There were 200 people in Husayn's caravan, many of whom were women, including his sisters, wives, daughters and their children. The women and children from Husayn's camp were taken as prisoners of war and led back to Damascus to be presented to Yazid I. They remained imprisoned until public opinion turned against him as word of Husayn's death and his family's capture spread. They were then granted passage back to Medina. The sole adult male survivor from the caravan was Ali ibn Husayn who was with fever too ill to fight when the caravan was attacked.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did Ubayd-Allah bin Ziyad rule?
Ah, so..
Basrah
