A. The intake valve is closed and the exhaust valve is open. \n    B. The intake valve is open and the exhaust valve is closed. \n    C. Both the intake valve and the exhaust valve are closed. \n    D. Both the intake valve and the exhaust valve are open

In simplest terms, the valves move like this:\n\n1.  Piston down - intake open, exhaust closed (injecting fuel)\n2.  Piston up - intake closed, exhaust closed (compressing fuel)\n3.  Piston down - intake closed, exhaust closed (igniting fuel)\n4.  Piston up - intake clsoed, exhaust open (expelling gas)\n\n(The exhaust valve opens earlier than in step 4, but it's easier to write it this way.)\n\nSo for the power stage of the 4-stroke cycle (the ignition of the fuel), the valves are closed.  Answer D.

water fountain, stop-lights, and blinker (or turn signal). never heard of the term 'bubbler', maybe i should use that from now on. I'm from so-cal.

Ultimately the valve should be open 60%. This is a fail open valve which means it is fully open at 0psi instrument air supply. An instrument air signal is 3-15psi range, meaning in the case of a fail open valve that 3psi is valve just starting to close, 6psi valve is closed 25%, 9psi closed 50%, 12psi closed 75%, and 15psi fully closed. your application is 7.8 psi supply which is 4.8psi above the start of the range (3psi) putting the valve 40% closed and in turn making it 60% open. \n\n    3psi  /      6psi   /       9psi   /     12psi    /    15psi\n    0%   /       25%  /       50%  /      75%     /    100%\n\nThere may be some speculators to this question because the adverse condition is the fail open valve, if the question was formed to apply to a fail closed valve the answer would be 40%open and 60% closed.

okay, here are the real correct answers:\n\n#1) a subject complement is an adjective that describes the main subject of the sentence. So in this case, B is the only one that comes close to that. The other three sentences all have direct objects, which are not subject complements.\n\n#2) C is correct. the other three sentences are not in correct syntax at all.\n\n#3) D is correct. muffler and spark plugs, more than one subject. "need" is the correct verb for plural subjects.
