Input: Read this: Many ground crew at the airport work at the aircraft. A tow tractor pulls the aircraft to one of the airbridges, The ground power unit is plugged in. It keeps the electricity running in the plane when it stands at the terminal. The engines are not working, therefore they do not generate the electricity, as they do in flight. The passengers disembark using the airbridge. Mobile stairs can give the ground crew more access to the aircraft's cabin. There is a cleaning service to clean the aircraft after the aircraft lands. Flight catering provides the food and drinks on flights. A toilet waste truck removes the human waste from the tank which holds the waste from the toilets in the aircraft. A water truck fills the water tanks of the aircraft. A fuel transfer vehicle transfers aviation fuel from fuel tanks underground, to the aircraft tanks. A tractor and its dollies bring in luggage from the terminal to the aircraft. They also carry luggage to the terminal if the aircraft has landed, and is being unloaded. Hi-loaders lift the heavy luggage containers to the gate of the cargo hold. The ground crew push the luggage containers into the hold. If it has landed, they rise, the ground crew push the luggage container on the hi-loader, which carries it down. The luggage container is then pushed on one of the tractors dollies. The conveyor, which is a conveyor belt on a truck, brings in the awkwardly shaped, or late luggage. The airbridge is used again by the new passengers to embark the aircraft. The tow tractor pushes the aircraft away from the terminal to a taxi area. The aircraft should be off of the airport and in the air in 90 minutes. The airport charges the airline for the time the aircraft spends at the airport.
Question: What does the ground crew use the skybridge to bring in after its pushed on one of the tractor dollies?

QUES: Nonverbal communication describes the process of conveying meaning in the form of non-word messages. Examples of nonverbal communication include haptic communication, chronemic communication, gestures, body language, facial expression, eye contact, and how one dresses. Nonverbal communication also relates to intent of a message. Examples of intent are voluntary, intentional movements like shaking a hand or winking, as well as involuntary, such as sweating. Speech also contains nonverbal elements known as paralanguage, e.g. rhythm, intonation, tempo, and stress. There may even be a pheromone component. Research has shown that up to 55% of human communication may occur through non-verbal facial expressions, and a further 38% through paralanguage. It affects communication most at the subconscious level and establishes trust. Likewise, written texts include nonverbal elements such as handwriting style, spatial arrangement of words and the use of emoticons to convey emotion.

What is one example of nonverbal communication?

ANS: body language

QUES: The ancestors of modern bacteria were unicellular microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago. For about 3 billion years, most organisms were microscopic, and bacteria and archaea were the dominant forms of life. In 2008, fossils of macroorganisms were discovered and named as the Francevillian biota. Although bacterial fossils exist, such as stromatolites, their lack of distinctive morphology prevents them from being used to examine the history of bacterial evolution, or to date the time of origin of a particular bacterial species. However, gene sequences can be used to reconstruct the bacterial phylogeny, and these studies indicate that bacteria diverged first from the archaeal/eukaryotic lineage. Bacteria were also involved in the second great evolutionary divergence, that of the archaea and eukaryotes. Here, eukaryotes resulted from the entering of ancient bacteria into endosymbiotic associations with the ancestors of eukaryotic cells, which were themselves possibly related to the Archaea. This involved the engulfment by proto-eukaryotic cells of alphaproteobacterial symbionts to form either mitochondria or hydrogenosomes, which are still found in all known Eukarya (sometimes in highly reduced form, e.g. in ancient "amitochondrial" protozoa). Later on, some eukaryotes that already contained mitochondria also engulfed cyanobacterial-like organisms. This led to the formation of chloroplasts in algae and plants. There are also some algae that originated from even later endosymbiotic events. Here, eukaryotes engulfed a eukaryotic algae that developed into a "second-generation" plastid. This is known as secondary endosymbiosis.
What are Stromatolites?

ANS: bacterial fossils

The FBI Laboratory, established with the formation of the BOI, did not appear in the J. Edgar Hoover Building until its completion in 1974. The lab serves as the primary lab for most DNA, biological, and physical work. Public tours of FBI headquarters ran through the FBI laboratory workspace before the move to the J. Edgar Hoover Building. The services the lab conducts include Chemistry, Combined DNA Index System (CODIS), Computer Analysis and Response, DNA Analysis, Evidence Response, Explosives, Firearms and Tool marks, Forensic Audio, Forensic Video, Image Analysis, Forensic Science Research, Forensic Science Training, Hazardous Materials Response, Investigative and Prospective Graphics, Latent Prints, Materials Analysis, Questioned Documents, Racketeering Records, Special Photographic Analysis, Structural Design, and Trace Evidence. The services of the FBI Laboratory are used by many state, local, and international agencies free of charge. The lab also maintains a second lab at the FBI Academy.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is not a service the lab conducts?
Ah, so.. unanswerable

Question: At the outset of the Franco-Prussian War, 462,000 German soldiers concentrated on the French frontier while only 270,000 French soldiers could be moved to face them, the French army having lost 100,000 stragglers before a shot was fired through poor planning and administration. This was partly due to the peacetime organisations of the armies. Each Prussian Corps was based within a Kreis (literally "circle") around the chief city in an area. Reservists rarely lived more than a day's travel from their regiment's depot. By contrast, French regiments generally served far from their depots, which in turn were not in the areas of France from which their soldiers were drawn. Reservists often faced several days' journey to report to their depots, and then another long journey to join their regiments. Large numbers of reservists choked railway stations, vainly seeking rations and orders.
Try to answer this question if possible: What is the literal meaning of the Prussian word "Kreis?"
Answer: literally "circle"

Context and question: Everton also have links with Chilean team Everton de Vina del Mar who were named after the English club. On 4 August 2010, the two Evertons played each other in a friendly named the Copa Hermandad at Goodison Park to mark the centenary of the Chilean team, an occasion organised by The Ruleteros Society, a society founded to promote connections between the two clubs. Other Evertons exist in Rosario in Colonia Department, Uruguay, La Plata, and Rio Cuarto in Argentina, Elk Grove, California in the United States, and in Cork, Ireland.
In what year did Cork, Ireland's Everton team first play?
Answer:
unanswerable
