Chickens arrived in Egypt some 250 years later, as fighting birds and additions to exotic menageries. Artistic depictions of the bird adorned royal tombs. Yet it would be another 1,000 years before the bird became a popular commodity among ordinary Egyptians. It was in that era that Egyptians mastered the technique of artificial incubation, which freed hens to put their time to better use by laying more eggs. This was no easy matter. Most chicken eggs will hatch in three weeks, but only if the temperature is kept constant at around 99 to 105 degrees Fahrenheit and the relative humidity stays close to 55 percent, increasing in the last few days of incubation. The eggs must also be turned three to five times a day, lest physical deformities result.
Section II lasts for a total of 100 minutes, and it includes a document-based question (DBQ) and a long essay question (LEQ). Students are allowed to work on either essay within this total time period. The section begins with a 15 minute reading period where students are advised to read both the documents for DBQ. However, students may begin writing during this time; most students take notes on the documents in order to plan out the DBQ. Students are advised to spend 45 minutes writing the DBQ and then 40 writing the LEQ, but there are no rules on when each essay must be worked on. There are three prompts for the LEQ, but only one needs to be chosen. Each LEQ prompt addresses a different period, with one addressing periods 1 & 2, another addressing periods 3 & 4, and a third addressing periods 5 & 6.
