How can the Federal Emergency Alert system reach people on the Internet?
A number of observers picked up on the fact the Emergency Alert System seems irrelevant without the participation of social media. How would cord-cutters watching Netflix, Hulu, and YouTube learn about the emergency? http://gizmodo.com/5857897/this-... I would make a parallel observation that the Emergency Alert System is irrelevant precisely because people are increasingly plugged into social media 24/7. Think about the recent DC earthquake: the tweets traveled faster than the shockwaves did through the earth. Someone on the outside periphery of the earthquake could have learned about it on Twitter before the earth started shaking. And this was for an event that lasted all of 30 seconds. The same could be said about how quickly news traveled about the death of Osama bin Laden. It happened late on a Sunday night, and the ratings for a late night Presidential address were far greater than any other recent speech President Obama has given when people were typically awake. Television played a huge role in alerting people about this breaking news event, but surveys after the fact showed that a significant number of people learned about it through social media, not from a centralized post from the government, but from their friends. God forbid there should there be a catastrophic event warranting the use of the Emergency Alert System, images of it would likely be captured on numerous camera phones and retweeted instantly. A number of people have speculated about what it would have been like had Twitter been around on 9/11, but at a minimum, the broad understanding that this was a deliberate terrorist attack would probably have occurred nearly instantaneously, as opposed to the uncertainty and speculation that preceded the second plane hitting the second tower. In the first minutes of a true emergency, getting out the raw story directly from the scene may be more important than getting a centralized message out quickly, particularly when the facts are necessarily unclear. To those who wonder what will happen if Twitter isn't included in the Emergency Alert System, I would say that Twitter is the Emergency Alert System.
Why did the pharoah set the jews free at the time of the passover?
Passover was to memorialize Pharoah setting the Jews free, not a case of Pharaoh coincindentally doing it at thast time. The first Passover (Exodus 12) was because the Lord knew what was going to happen, and Pharoah's reaction.
Which one is correct? “please let me know if you have any question” or ”please let me know if you have any questions”
"Question" is not ungrammatical, but "questions" is much more usual. It's more a matter of logic and courtesy than grammar: "question" presumes/implies that the listener is allowed only one question, which is a bit imperious.
