Problem: Electric motor:

The rotating armature consists of one or more coils of wire wound around a laminated, magnetically "soft" ferromagnetic core. Current from the brushes flows through the commutator and one winding of the armature, making it a temporary magnet (an electromagnet). The magnetic field produced by the armature interacts with a stationary magnetic field produced by either PMs or another winding a field coil, as part of the motor frame. The force between the two magnetic fields tends to rotate the motor shaft. The commutator switches power to the coils as the rotor turns, keeping the magnetic poles of the rotor from ever fully aligning with the magnetic poles of the stator field, so that the rotor never stops (like a compass needle does), but rather keeps rotating as long as power is applied.

What element of the motor makes the poles alligning?

Problem: United States Air Force:

Since 2005, the USAF has placed a strong focus on the improvement of Basic Military Training (BMT) for enlisted personnel. While the intense training has become longer, it also has shifted to include a deployment phase. This deployment phase, now called the BEAST, places the trainees in a surreal environment that they may experience once they deploy. While the trainees do tackle the massive obstacle courses along with the BEAST, the other portions include defending and protecting their base of operations, forming a structure of leadership, directing search and recovery, and basic self aid buddy care. During this event, the Military Training Instructors (MTI) act as mentors and enemy forces in a deployment exercise.

What did the USAF strive to improve since 2005?

A: Basic Military Training

Problem: Dutch language:

Like most Germanic languages, Dutch forms noun compounds, where the first noun modifies the category given by the second (hondenhok = doghouse). Unlike English, where newer compounds or combinations of longer nouns are often written in open form with separating spaces, Dutch (like the other Germanic languages) either uses the closed form without spaces (boomhuis = tree house) or inserts a hyphen (VVD-coryfee = outstanding member of the VVD, a political party). Like German, Dutch allows arbitrarily long compounds, but the longer they get, the less frequent they tend to be.

How would a Dutch speaker say "doghouse"?

A: hondenhok

Problem: Armenians:

Historically, the name Armenian has come to internationally designate this group of people. It was first used by neighbouring countries of ancient Armenia. The earliest attestations of the exonym Armenia date around the 6th century BC. In his trilingual Behistun Inscription dated to 517 BC, Darius I the Great of Persia refers to Urashtu (in Babylonian) as Armina (in Old Persian; Armina ( ) and Harminuya (in Elamite). In Greek, "Armenians" is attested from about the same time, perhaps the earliest reference being a fragment attributed to Hecataeus of Miletus (476 BC). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians.

What did Hecateus of Miletus believe the people's language sounded like?
