Problem: Nintendo Entertainment System:

The system was originally targeted for release in the spring of 1985, but the release date was pushed back. After test-marketing in the New York City area in late fall, retailers had reportedly stated the system "failed miserably".[contradictory] While others stated that Nintendo had an excellent nine-week market test in New York last fall Due to the moderate success launch in New York City, Nintendo tried a second time; the system was test-marketed further beginning in February 1986, with the nationwide release occurring in September 1986.

When was the second time Nintendo test marketed the NES?

A: February 1986

Problem: Cotton:

But Bt cotton is ineffective against many cotton pests, however, such as plant bugs, stink bugs, and aphids; depending on circumstances it may still be desirable to use insecticides against these. A 2006 study done by Cornell researchers, the Center for Chinese Agricultural Policy and the Chinese Academy of Science on Bt cotton farming in China found that after seven years these secondary pests that were normally controlled by pesticide had increased, necessitating the use of pesticides at similar levels to non-Bt cotton and causing less profit for farmers because of the extra expense of GM seeds. However, a 2009 study by the Chinese Academy of Sciences, Stanford University and Rutgers University refuted this. They concluded that the GM cotton effectively controlled bollworm. The secondary pests were mostly miridae (plant bugs) whose increase was related to local temperature and rainfall and only continued to increase in half the villages studied. Moreover, the increase in insecticide use for the control of these secondary insects was far smaller than the reduction in total insecticide use due to Bt cotton adoption. A 2012 Chinese study concluded that Bt cotton halved the use of pesticides and doubled the level of ladybirds, lacewings and spiders. The International Service for the Acquisition of Agri-biotech Applications (ISAAA) said that, worldwide, GM cotton was planted on an area of 25 million hectares in 2011. This was 69% of the worldwide total area planted in cotton.

On what did a 2009 study conclude that increased insects were dependent?
---
A: temperature and rainfall

Problem: Symbiosis:

Another non-obligate symbiosis is known from encrusting bryozoans and hermit crabs that live in a close relationship. The bryozoan colony (Acanthodesia commensale) develops a cirumrotatory growth and offers the crab (Pseudopagurus granulimanus) a helicospiral-tubular extension of its living chamber that initially was situated within a gastropod shell.

What relationship is it considered when the bryozoans and hermit crabs do not live in a close relationship?
---
A: unanswerable

Problem: Greeks:

The history of the Greek people is closely associated with the history of Greece, Cyprus, Constantinople, Asia Minor and the Black Sea. During the Ottoman rule of Greece, a number of Greek enclaves around the Mediterranean were cut off from the core, notably in Southern Italy, the Caucasus, Syria and Egypt. By the early 20th century, over half of the overall Greek-speaking population was settled in Asia Minor (now Turkey), while later that century a huge wave of migration to the United States, Australia, Canada and elsewhere created the modern Greek diaspora.

After the 19th century about how much of the Greek population resided in little Asia ?
