Input: Read this: Insects were among the earliest terrestrial herbivores and acted as major selection agents on plants. Plants evolved chemical defenses against this herbivory and the insects, in turn, evolved mechanisms to deal with plant toxins. Many insects make use of these toxins to protect themselves from their predators. Such insects often advertise their toxicity using warning colors. This successful evolutionary pattern has also been used by mimics. Over time, this has led to complex groups of coevolved species. Conversely, some interactions between plants and insects, like pollination, are beneficial to both organisms. Coevolution has led to the development of very specific mutualisms in such systems.
Question: What did plants eventually form against insects?

Output: chemical defenses

QUES: The USAF countered the MiG-15 by sending over three squadrons of its most capable fighter, the F-86 Sabre. These arrived in December 1950. The MiG was designed as a bomber interceptor. It had a very high service ceiling50,000 feet (15,000 m) and carried very heavy weaponry: one 37 mm cannon and two 23 mm cannons. They were fast enough to dive past the fighter escort of P-80 Shooting Stars and F9F Panthers and could reach and destroy the U.S. heavy bombers. B-29 losses could not be avoided, and the Air Force was forced to switch from a daylight bombing campaign to the necessarily less accurate nighttime bombing of targets. The MiGs were countered by the F-86 Sabres. They had a ceiling of 42,000 feet (13,000 m) and were armed with six .50 caliber (12.7 mm) machine guns, which were range adjusted by radar gunsights. If coming in at higher altitude the advantage of engaging or not went to the MiG. Once in a level flight dogfight, both swept-wing designs attained comparable maximum speeds of around 660 mph (1,100 km/h). The MiG climbed faster, but the Sabre turned and dived better.

What plane did the US send to Korea to counter the power of the MiG-15?
What is the answer?
ANS: F-86 Sabre

QUES: Areas such as South Street and Old City have a vibrant night life. The Avenue of the Arts in Center City contains many restaurants and theaters, such as the Kimmel Center for the Performing Arts, which is home to the Philadelphia Orchestra, generally considered one of the top five orchestras in the United States, and the Academy of Music, the nation's oldest continually operating opera house, home to the Opera Company of Philadelphia and the Pennsylvania Ballet. The Wilma Theatre and Philadelphia Theatre Company have new buildings constructed in the last decade on the avenue. They produce a variety of new works. Several blocks to the east are the Walnut Street Theatre, America's oldest theatre and the largest subscription theater in the world; as well as the Lantern Theatre at St. Stephens Church, one of a number of smaller venues.
What is the oldest theater in the U.S.?

ANS: Walnut Street Theatre

In addition to the change in the mean length of the calendar year from 365.25 days (365 days 6 hours) to 365.2425 days (365 days 5 hours 49 minutes 12 seconds), a reduction of 10 minutes 48 seconds per year, the Gregorian calendar reform also dealt with the accumulated difference between these lengths. The canonical Easter tables were devised at the end of the third century, when the vernal equinox fell either on 20 March or 21 March depending on the year's position in the leap year cycle. As the rule was that the full moon preceding Easter was not to precede the equinox the equinox was fixed at 21 March for computational purposes and the earliest date for Easter was fixed at 22 March. The Gregorian calendar reproduced these conditions by removing ten days.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In order to account for the full moon coming after the equinox, when was the equinox set?
Ah, so.. 22 March

Question: Speculation that the Ashkenazi arose from Khazar stock surfaced in the later 19th century and has met with mixed fortunes in the scholarly literature. In late 2012 Eran Elhaik, a research associate studying genetics at the Johns Hopkins University School of Public Health, argued for Khazar descent in his paper The Missing Link of Jewish European Ancestry: Contrasting the Rhineland and the Khazarian Hypotheses. A 2013 study of Ashkenazi mitochondrial DNA found no significant evidence of Khazar contribution to the Ashkenazi Jewish DNA, as would be predicted by the Khazar hypothesis.
Try to answer this question if possible: Did Eran Elhaik, from Johns Hopkins University School of Public Health argue for or against Khazar descent?
Answer: argued for Khazar descent
