Here is a question about this article: Cotton remained a key crop in the Southern economy after emancipation and the end of the Civil War in 1865. Across the South, sharecropping evolved, in which landless black and white farmers worked land owned by others in return for a share of the profits. Some farmers rented the land and bore the production costs themselves. Until mechanical cotton pickers were developed, cotton farmers needed additional labor to hand-pick cotton. Picking cotton was a source of income for families across the South. Rural and small town school systems had split vacations so children could work in the fields during "cotton-picking."
What is the answer to this question: What function of southern schools was created for children to pick cotton?
****
So... split vacations

Problem: Please answer a question about the following article about History of India:
The subsequent Slave dynasty of Delhi managed to conquer large areas of northern India, while the Khilji dynasty conquered most of central India but were ultimately unsuccessful in conquering and uniting the subcontinent. The Sultanate ushered in a period of Indian cultural renaissance. The resulting "Indo-Muslim" fusion of cultures left lasting syncretic monuments in architecture, music, literature, religion, and clothing. It is surmised that the language of Urdu (literally meaning "horde" or "camp" in various Turkic dialects) was born during the Delhi Sultanate period as a result of the intermingling of the local speakers of Sanskritic Prakrits with immigrants speaking Persian, Turkic, and Arabic under the Muslim rulers. The Delhi Sultanate is the only Indo-Islamic empire to enthrone one of the few female rulers in India, Razia Sultana (12361240).
Who was the only female sultana to be enthroned in a Indo-Islamic empire?
A: Razia Sultana

Problem: Short-term memory is supported by transient patterns of neuronal communication, dependent on regions of the frontal lobe (especially dorsolateral prefrontal cortex) and the parietal lobe. Long-term memory, on the other hand, is maintained by more stable and permanent changes in neural connections widely spread throughout the brain. The hippocampus is essential (for learning new information) to the consolidation of information from short-term to long-term memory, although it does not seem to store information itself. Without the hippocampus, new memories are unable to be stored into long-term memory, as learned from patient Henry Molaison after removal of both his hippocampi, and there will be a very short attention span. Furthermore, it may be involved in changing neural connections for a period of three months or more after the initial learning.
Which part of the brain does short-term memory seem to rely on?
The answer is the following: frontal lobe (especially dorsolateral prefrontal cortex) and the parietal lobe
