Avoid answers that are incorrect or provides incomplete justification for the question.

[EX Q]: Passage: Miami is the southern terminus of Amtrak's Atlantic Coast services, running two lines, the Silver Meteor and the Silver Star, both terminating in New York City. The Miami Amtrak Station is located in the suburb of Hialeah near the Tri-Rail/Metrorail Station on NW 79 St and NW 38 Ave. Current construction of the Miami Central Station will move all Amtrak operations from its current out-of-the-way location to a centralized location with Metrorail, MIA Mover, Tri-Rail, Miami International Airport, and the Miami Intermodal Center all within the same station closer to Downtown. The station was expected to be completed by 2012, but experienced several delays and was later expected to be completed in late 2014, again pushed back to early 2015. Question: In what year was the Miami Central Station originally supposed to have been completed?
[EX A]: 2012

[EX Q]: Passage: During its formative period, the term madrasah referred to a higher education institution, whose curriculum initially included only the "religious sciences", whilst philosophy and the secular sciences were often excluded. The curriculum slowly began to diversify, with many later madaris teaching both the religious and the "secular sciences", such as logic, mathematics and philosophy. Some madaris further extended their curriculum to history, politics, ethics, music, metaphysics, medicine, astronomy and chemistry. The curriculum of a madrasah was usually set by its founder, but most generally taught both the religious sciences and the physical sciences. Madaris were established throughout the Islamic world, examples being the 9th century University of al-Qarawiyyin, the 10th century al-Azhar University (the most famous), the 11th century Niẓāmīyah, as well as 75 madaris in Cairo, 51 in Damascus and up to 44 in Aleppo between 1155 and 1260. Many more were also established in the Andalusian cities of Córdoba, Seville, Toledo, Granada (Madrasah of Granada), Murcia, Almería, Valencia and Cádiz during the Caliphate of Córdoba. Question: Who decided the content that would be delivered in a particular madrasah?
[EX A]: its founder

[EX Q]: Passage: Because of their long life, fast switching times, and their ability to be seen in broad daylight due to their high output and focus, LEDs have been used in brake lights for cars' high-mounted brake lights, trucks, and buses, and in turn signals for some time, but many vehicles now use LEDs for their rear light clusters. The use in brakes improves safety, due to a great reduction in the time needed to light fully, or faster rise time, up to 0.5 second faster[citation needed] than an incandescent bulb. This gives drivers behind more time to react. In a dual intensity circuit (rear markers and brakes) if the LEDs are not pulsed at a fast enough frequency, they can create a phantom array, where ghost images of the LED will appear if the eyes quickly scan across the array. White LED headlamps are starting to be used. Using LEDs has styling advantages because LEDs can form much thinner lights than incandescent lamps with parabolic reflectors. Question: What color LEDs are now starting to be used more?
[EX A]:
White
