Problem: Symbiosis:

A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This gut flora is made up of cellulose-digesting protozoans or bacteria living in the herbivores' intestines. Coral reefs are the result of mutualisms between coral organisms and various types of algae that live inside them. Most land plants and land ecosystems rely on mutualisms between the plants, which fix carbon from the air, and mycorrhyzal fungi, which help in extracting water and minerals from the ground.

Where do the mycorrhyzal fungi go to after extracting water and minerals from the ground?

Problem: In the early 20th century, the vast conscription of Italian men from all throughout Italy during World War I is credited with facilitating the diffusion of standard Italian among less educated Italian men, as these men from various regions with various regional languages were forced to communicate with each other in a common tongue while serving in the Italian military. With the eventual spread of the radio and television throughout Italy and the establishment of public education, Italians from all regions were increasingly exposed to standard Italian, while literacy rates among all social classes improved. Today, the majority of Italians are able to speak standard Italian, though many Italians still speak their regional language regularly or as their primary day-to-day language, especially at home with family or when communicating with Italians from the same town or region. However, to some Italians, speaking a regional language, especially in a formal setting or outside of one's region, may carry a stigma or negative connotations associated with being lower class, uneducated, boorish, or overly informal.
What is never associated with being boorish?

The following year, the group released their self-titled debut album, scoring their first major hit "No, No, No". The album established the group as a viable act in the music industry, with moderate sales and winning the group three Soul Train Lady of Soul Awards for Best R&B/Soul Album of the Year, Best R&B/Soul or Rap New Artist, and Best R&B/Soul Single for "No, No, No". The group released their multi-platinum second album The Writing's on the Wall in 1999. The record features some of the group's most widely known songs such as "Bills, Bills, Bills", the group's first number-one single, "Jumpin' Jumpin'" and "Say My Name", which became their most successful song at the time, and would remain one of their signature songs. "Say My Name" won the Best R&B Performance by a Duo or Group with Vocals and the Best R&B Song at the 43rd Annual Grammy Awards. The Writing's on the Wall sold more than eight million copies worldwide. During this time, Beyoncé recorded a duet with Marc Nelson, an original member of Boyz II Men, on the song "After All Is Said and Done" for the soundtrack to the 1999 film, The Best Man.
What singer did Beyonce record a song with for the movie, ''The Best Man"?

Context and question: Until the 19th century, religion played a significant role in university curriculum; however, the role of religion in research universities decreased in the 19th century, and by the end of the 19th century, the German university model had spread around the world. Universities concentrated on science in the 19th and 20th centuries and became increasingly accessible to the masses. In Britain, the move from Industrial Revolution to modernity saw the arrival of new civic universities with an emphasis on science and engineering, a movement initiated in 1960 by Sir Keith Murray (chairman of the University Grants Committee) and Sir Samuel Curran, with the formation of the University of Strathclyde. The British also established universities worldwide, and higher education became available to the masses not only in Europe.
Ending with what century did religion play a smaller part in the curriculum of universities?
Answer: 19th


Question: The National Incident Based Reporting System (NIBRS) crime statistics system aims to address limitations inherent in UCR data. The system is used by law enforcement agencies in the United States for collecting and reporting data on crimes. Local, state, and federal agencies generate NIBRS data from their records management systems. Data is collected on every incident and arrest in the Group A offense category. The Group A offenses are 46 specific crimes grouped in 22 offense categories. Specific facts about these offenses are gathered and reported in the NIBRS system. In addition to the Group A offenses, eleven Group B offenses are reported with only the arrest information. The NIBRS system is in greater detail than the summary-based UCR system. As of 2004, 5,271 law enforcement agencies submitted NIBRS data. That amount represents 20% of the United States population and 16% of the crime statistics data collected by the FBI.
Is there an answer to this question: What does the NIBRS collect information on?

Answer: crimes


High-power LEDs (HP-LEDs) or high-output LEDs (HO-LEDs) can be driven at currents from hundreds of mA to more than an ampere, compared with the tens of mA for other LEDs. Some can emit over a thousand lumens. LED power densities up to 300 W/cm2 have been achieved. Since overheating is destructive, the HP-LEDs must be mounted on a heat sink to allow for heat dissipation. If the heat from a HP-LED is not removed, the device will fail in seconds. One HP-LED can often replace an incandescent bulb in a flashlight, or be set in an array to form a powerful LED lamp.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many lumens can some high-power LEDs emit?
Ah, so..
over a thousand
