I'm not exactly sure what subject this is, but hopefully my answer can help you just a little bit :)
Any driver must stay alert for any incoming cars or pay attention to traffic lights. In a city, there's a lot of bustling so signal everytime you want to cut in front of someone and pay attention if anyone else signals.
I personally disagree with the Electoral College. It was a system that worked 200 years ago. The system now just doesn’t work because we have all these things like mail in voting, claimed election fraud, etc. Not only that but the electoral college could have a bias against a candidate. If you look at Hilary Clinton for example. She ran for President in 2016 but ended up losing the Electoral College vote but won the popular vote. Now she is an electoral college member which obviously, she wouldn’t vote for trump. The only reason the Electoral College is because the original framers said that the president and Vice President should be decided by a set group of people. Which today, is the Electoral College. Hope this helps!
I haven’t learnt this, but the encyclopedia says it increases in national income so i assume it’s the first one because they’re both about income but i’m not sure so i’m sorry if its wrong ;-;
