Context and question: Infrared tracking, also known as infrared homing, refers to a passive missile guidance system, which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track it. Missiles that use infrared seeking are often referred to as "heat-seekers", since infrared (IR) is just below the visible spectrum of light in frequency and is radiated strongly by hot bodies. Many objects such as people, vehicle engines, and aircraft generate and retain heat, and as such, are especially visible in the infrared wavelengths of light compared to objects in the background.
What is the term that uses the infrared spectrum that is radiated by hot bodies?
Answer: unanswerable
Context and question: As with personae in general, a character's face or heel alignment may change with time, or remain constant over its lifetime (the most famous example of the latter is Ricky Steamboat, a WWE Hall of Famer who remained a babyface throughout his entire career). Sometimes a character's heel turn will become so popular that eventually the audience response will alter the character's heel-face cycle to the point where the heel persona will, in practice, become a face persona, and what was previously the face persona, will turn into the heel persona, such as when Dwayne Johnson first began using "The Rock" persona as a heel character, as opposed to his original "Rocky Maivia" babyface persona. Another legendary example is Stone Cold Steve Austin, who was originally booked as a heel, with such mannerisms as drinking on the job, using profanity, breaking company property, and even breaking into people's private homes. However, much to WWF's surprise, the fans enjoyed Austin's antics so much that he became one of the greatest antiheroes in the history of the business. He, along with the stable of D-Generation X, is generally credited with ushering in the Attitude Era of WWF programming.
What did Stone Cold Steve Austin start as? 
Answer: heel
Context and question: Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.
The sand and clay deposited onto decaying marine matter transformed into what?
Answer:
oil and natural gas
