[EX Q]: [header] How to determine who has right of way [title] Come to a complete halt at a stop sign or red light. [step] At a stop sign, come to complete halt for about 2 seconds or until vehicles that arrived before you clear the intersection. If you're stopped at a red light, proceed when the light has turned green. <sep> (A) This will give you enough time to catch the light and clear the intersection. [substeps] Vehicles behind or behind you may not brake. (B) This blocks oncoming cars from passing you. [substeps] If in doubt, you can also tell if you're going too fast by looking ahead at the tires of that car. (C) If you are stopped before a red light signals for another vehicle, you're on your own. [substeps] This means every car crossed before you has passed, and every vehicle in the intersection has stopped before you. (D) If the intersection has a white stripe in your lane, stop before this line. [substeps] If you have a stop sign, but the street you're crossing does not have a stop sign, wait until all traffic has cleared before crossing the intersection.

[EX Q]: [header] How to help paranoid people [title] Avoid arguing with the person. [step] When your friend or family member expresses delusional thoughts, listen to them, but don't argue. The delusion seems completely real to them, so you won't be able to talk them into believing something else. <sep> (A) Disagreeing will only make the delusion worse. [title] Stay calm if the person tries to change the topic. (B) [substeps] Say, " why are you talking that way? Is this really something you can actually do? " ignoring what your friend said is always easier than arguing. If the person is so obsessed with believing them, it's okay for them to indulge in delusions. (C) [substeps] Arguing can even make the situation worse, since it will make the person feel like no one understands them. [title] Avoid affirming the person's paranoia. (D) [substeps] If you must argue, try to remain non-accusatory (" i'm wrong. That doesn't make sense " is better).
