PLEASE HELP ME ITS DUE IN NEXT 2 HOURS

1) The correct answer is crude oil. The reason crude oil is the "mother of all commodities," is because it is not only used for gasoline, but also to make plastic, paint, and other petroleum products.  For the first time in history, on Monday the price of oil temporarily became negative (-37.63). Obviously with the pandemic, less oil and gas are being used, thus oil prices are falling as suppliers look for places to store their product until supply picks back up.

2) The two word term is "ice shoves," and they are occurring in northern Minnesota, where one individual has a 30 foot wall of ice approaching his house.An "ice shove" is exactly what it sounds like, melting ice piling up on a lake shore after being pushed there by the wind.

3) Sweden is the European country in which a top disease specialist says there are signals of herd immunity. Herd immunity is when at least 60 per cent of a community becomes immune to an infectious disease. The specialist indicated that around the city of Stockholm his study suggests there is this herd immunity. Sweden did not close down for the pandemic and has recorded 2,000 deaths, while Norway and Finland around 200 deaths.
