Q: In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. This dilutes the O in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce peak in-cylinder temperatures. NO is produced in a narrow band of high cylinder temperatures and pressures. Another primary benefit of external EGR valves on a spark ignition engine is an increase in efficiency, as charge dilution allows a larger throttle position and reduces associated pumping losses.
Can we conclude that is the egr valve part of the engine?

Problem: Text: The Mississippi River has the world's fourth-largest drainage basin (''watershed'' or ''catchment''). The basin covers more than 1,245,000 square miles (3,220,000 km), including all or parts of 31 U.S. states and two Canadian provinces. The drainage basin empties into the Gulf of Mexico, part of the Atlantic Ocean. The total catchment of the Mississippi River covers nearly 40% of the landmass of the continental United States. The highest point within the watershed is also the highest point of the Rocky Mountains, Mount Elbert at 14,440 feet (4,400 m).

IN: Is it true that are you a us citizen if born in the us?

Birthright citizenship in the United States is acquired by virtue of the circumstances of birth. It contrasts with citizenship acquired in other ways, for example by naturalization. Birthright citizenship may be conferred by jus soli or jus sanguinis. Under United States law, U.S. citizenship is automatically granted to any person born within and subject to the jurisdiction of the United States. This includes the territories of Puerto Rico, the Marianas (Guam and the Northern Mariana Islands), and the U.S. Virgin Islands, and also applies to children born elsewhere in the world to U.S. citizens (with certain exceptions).
