Extract the answer to the question from the following context. Question: Which of the following is NOT caused by circadian disruption: breast cancer, Alzheimer's Disease, or delayed sleep phase syndrome? Context: Analysis of lighting quality particularly emphasizes use of natural lighting, but also considers spectral content if artificial light is to be used. Not only will greater reliance on natural light reduce energy consumption, but will favorably impact human health and performance. New studies have shown that the performance of students is influenced by the time and duration of daylight in their regular schedules. Designing school facilities to incorporate the right types of light at the right time of day for the right duration may improve student performance and well-being. Similarly, designing lighting systems that maximize the right amount of light at the appropriate time of day for the elderly may help relieve symptoms of Alzheimer's Disease. The human circadian system is entrained to a 24-hour light-dark pattern that mimics the earth’s natural light/dark pattern. When those patterns are disrupted, they disrupt the natural circadian cycle. Circadian disruption may lead to numerous health problems including breast cancer, seasonal affective disorder, delayed sleep phase syndrome, and other ailments.

Extract the answer to the question from the following context. Question: What came from the error? Context: On March 1, 2010 (UTC), many of the original "fat" PlayStation 3 models worldwide were experiencing errors related to their internal system clock. The error had many symptoms. Initially, the main problem seemed to be the inability to connect to the PlayStation Network. However, the root cause of the problem was unrelated to the PlayStation Network, since even users who had never been online also had problems playing installed offline games (which queried the system timer as part of startup) and using system themes. At the same time many users noted that the console's clock had gone back to December 31, 1999. The event was nicknamed the ApocalyPS3, a play on the word apocalypse and PS3, the abbreviation for the PlayStation 3 console.

Extract the answer to the question from the following context. Question: What was the focus? Context: The era of planning in Himachal Pradesh started 1948 along with the rest of India. The first five-year plan allocated ₹ 52.7 million to Himachal. More than 50% of this expenditure was incurred on road construction since it was felt that without proper transport facilities, the process of planning and development could not be carried to the people, who mostly lived an isolated existence in far away areas. Himachal now ranks fourth in respect of per capita income among the states of the Indian Union.
