Problem: USB:

In addition to limiting the total average power used by the device, the USB specification limits the inrush current (i.e., that used to charge decoupling and filter capacitors) when the device is first connected. Otherwise, connecting a device could cause problems with the host's internal power. USB devices are also required to automatically enter ultra low-power suspend mode when the USB host is suspended. Nevertheless, many USB host interfaces do not cut off the power supply to USB devices when they are suspended.

Many USB host interfaces do not what?
---
A: cut off the power supply to USB devices when they are suspended

Problem: Eisenhower's goal to create improved highways was influenced by difficulties encountered during his involvement in the U.S. Army's 1919 Transcontinental Motor Convoy. He was assigned as an observer for the mission, which involved sending a convoy of U.S. Army vehicles coast to coast. His subsequent experience with encountering German autobahn limited-access road systems during the concluding stages of World War II convinced him of the benefits of an Interstate Highway System. Noticing the improved ability to move logistics throughout the country, he thought an Interstate Highway System in the U.S. would not only be beneficial for military operations, but provide a measure of continued economic growth. The legislation initially stalled in the Congress over the issuance of bonds to finance the project, but the legislative effort was renewed and the law was signed by Eisenhower in June 1956.
Why did Congress hold up the highway bill?
---
Answer: issuance of bonds to finance the project

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
During its formative period, the term madrasah referred to a higher education institution, whose curriculum initially included only the "religious sciences", whilst philosophy and the secular sciences were often excluded. The curriculum slowly began to diversify, with many later madaris teaching both the religious and the "secular sciences", such as logic, mathematics and philosophy. Some madaris further extended their curriculum to history, politics, ethics, music, metaphysics, medicine, astronomy and chemistry. The curriculum of a madrasah was usually set by its founder, but most generally taught both the religious sciences and the physical sciences. Madaris were established throughout the Islamic world, examples being the 9th century University of al-Qarawiyyin, the 10th century al-Azhar University (the most famous), the 11th century Nizamiyah, as well as 75 madaris in Cairo, 51 in Damascus and up to 44 in Aleppo between 1155 and 1260. Many more were also established in the Andalusian cities of Cordoba, Seville, Toledo, Granada (Madrasah of Granada), Murcia, Almeria, Valencia and Cadiz during the Caliphate of Cordoba.
How many madaris have been founded in Cairo?
A: 75

Context and question: While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.
Why is xenon gas widely used?
Answer: unanswerable

Question: The Illuminating Engineering Society of North America (IESNA), in conjunction with organizations like ANSI and ASHRAE, publishes guidelines, standards, and handbooks that allow categorization of the illumination needs of different built environments. Manufacturers of lighting equipment publish photometric data for their products, which defines the distribution of light released by a specific luminaire. This data is typically expressed in standardized form defined by the IESNA.
Is there an answer to this question: Who else publishes along with IESNA?

Answer: ANSI and ASHRAE

Problem: Anthropology:

Psychological anthropology is an interdisciplinary subfield of anthropology that studies the interaction of cultural and mental processes. This subfield tends to focus on ways in which humans' development and enculturation within a particular cultural groupwith its own history, language, practices, and conceptual categoriesshape processes of human cognition, emotion, perception, motivation, and mental health. It also examines how the understanding of cognition, emotion, motivation, and similar psychological processes inform or constrain our models of cultural and social processes.

What does psychological anthropology particularly focus on in a particular culture group?
---
A:
humans' development and enculturation
