Task: Question Answering
Input (English): Background Paragraph: Temperature is a measure of the average kinetic energy of the particles in matter. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was an increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased. Many unstable materials (such as enzymes) will be viable longer at lower temperatures. 
Story: John is a scientist. Yesterday, he conducted several tests, test A, test B, test C, test D, test E, and test F. In test A he kept a substance in solid state. Then in test B he changed the same substance to liquid state. In test C he conducted a chemical reaction in room temperature. Then in test D he conducted the same chemical reaction in higher temperature. In test E he kept some enzymes in high temperature. Finally, in test F he kept the same enzymes in lower temperature. 
Question: Would test D be faster or slower than test C?
Output (English): faster.
