[EX Q]: Question: Of the grasses that the essex skipper eats, which is the longest? Passage:Eggs are laid in strings on the stems of grasses where they remain over the winter. The Essex skipper's favoured foodplant is cock's-foot (Dactylis glomerata), and it rarely uses the small skipper's favoured foodplant Yorkshire fog. Essex skippers' other foods include creeping soft grass (Holcus mollis), couch grass (Elymus repens), timothy-grass (Phleum pratense), meadow foxtail (Alopecurus pratensis), false brome (Brachypodium sylvaticum) and tor-grass (Brachypodium pinnatum). This skipper's caterpillars emerge in the spring and feed until June before forming shelters from leaves tied with silk at the base of the foodplant to pupate. Adults fly from July through August. Like most skippers, they are fairly strictly diurnal, though individuals are very rarely encountered during the night.

[EX Q]: Question: Which countries comprised the alliance that conquered and occupied Greece? Passage:Aside from the Romaniotes, a distinct Jewish population that historically lived in communities throughout Greece and neighboring areas with large Greek populations, Greece had a large population of Sephardi Jews, and is a historical center of Sephardic life; the city of Salonica or Thessaloniki, in Greek Macedonia, was called the "Mother of Israel". Greek Jews played an important role in the early development of Christianity, and became a source of education and commerce for the Byzantine Empire and throughout the period of Ottoman Greece, until suffering devastation in the Holocaust after Greece was conquered and occupied by the Axis powers despite efforts by Greeks to protect them. In the aftermath of the Holocaust, a large percentage of the surviving community emigrated to Israel or the United States.
