Input: Read this: Everything in between the far south and the far north is savannah (insignificant tree cover, with grasses and flowers located between trees). Rainfall is more limited, to between 500 and 1,500 millimetres (20 and 60 in) per year. The savannah zone's three categories are Guinean forest-savanna mosaic, Sudan savannah, and Sahel savannah. Guinean forest-savanna mosaic is plains of tall grass interrupted by trees. Sudan savannah is similar but with shorter grasses and shorter trees. Sahel savannah consists of patches of grass and sand, found in the northeast. In the Sahel region, rain is less than 500 millimetres (20 in) per year and the Sahara Desert is encroaching. In the dry north-east corner of the country lies Lake Chad, which Nigeria shares with Niger, Chad and Cameroon.
Question: Which desert is encroaching into northeastern Nigeria?

Output: Sahara

QUES: BYU has been considered by some Latter-day Saints, as well as some university and church leaders, to be "The Lord's university". This phrase is used in reference to the school's mission as an "ambassador" to the world for the LDS Church and thus, for Jesus Christ. In the past, some students and faculty have expressed dissatisfaction with this nickname, stating that it gives students the idea that university authorities are always divinely inspired and never to be contradicted. Leaders of the school, however, acknowledge that the nickname represents more a goal that the university strives for and not its current state of being. Leaders encourage students and faculty to help fulfill the goal by following the teachings of their religion, adhering to the school's honor code, and serving others with the knowledge they gain while attending.
Who has expressed dissatisfaction with the nickname "The Lord's University" in the past?

ANS: some students and faculty

Jehovah's Witnesses have been accused of having policies and culture that help to conceal cases of sexual abuse within the organization. The religion has been criticized for its "two witness rule" for church discipline, based on its application of scriptures at Deuteronomy 19:15 and Matthew 18:15-17, which requires sexual abuse to be substantiated by secondary evidence if the accused person denies any wrongdoing. In cases where corroboration is lacking, the Watch Tower Society's instruction is that "the elders will leave the matter in Jehovah's hands". A former member of the church's headquarters staff, Barbara Anderson, says the policy effectively requires that there be another witness to an act of molestation, "which is an impossibility". Anderson says the policies "protect pedophiles rather than protect the children." Jehovah's Witnesses maintain that they have a strong policy to protect children, adding that the best way to protect children is by educating parents; they also state that they do not sponsor activities that separate children from parents.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What religion is one of the best at protecting children from molestation?
Ah, so.. unanswerable

Question: T. Gilmartin, (Professor of History, Maynooth, 1890), writes in Church History, Vol. 1, Ch XVII: On the death of Alexander, five months after the termination of the Council of Nice, Athanasius was unanimously elected to fill the vacant see. He was most unwilling to accept the dignity, for he clearly foresaw the difficulties in which it would involve him. The clergy and people were determined to have him as their bishop, Patriarch of Alexandria, and refused to accept any excuses. He at length consented to accept a responsibility that he sought in vain to escape, and was consecrated in 326, when he was about thirty years of age.
Try to answer this question if possible: Did Athanasius want to be the Patriarch of Alexandria?
Answer: He was most unwilling to accept

Context and question: However, memory performance can be enhanced when material is linked to the learning context, even when learning occurs under stress. A separate study by cognitive psychologists Schwabe and Wolf shows that when retention testing is done in a context similar to or congruent with the original learning task (i.e., in the same room), memory impairment and the detrimental effects of stress on learning can be attenuated. Seventy-two healthy female and male university students, randomly assigned to the SECPT stress test or to a control group, were asked to remember the locations of 15 pairs of picture cards a computerized version of the card game "Concentration" or "Memory". The room in which the experiment took place was infused with the scent of vanilla, as odour is a strong cue for memory. Retention testing took place the following day, either in the same room with the vanilla scent again present, or in a different room without the fragrance. The memory performance of subjects who experienced stress during the object-location task decreased significantly when they were tested in an unfamiliar room without the vanilla scent (an incongruent context); however, the memory performance of stressed subjects showed no impairment when they were tested in the original room with the vanilla scent (a congruent context). All participants in the experiment, both stressed and unstressed, performed faster when the learning and retrieval contexts were similar.
What can impact memory performance in a negative way?
