Problem: Ground Control is responsible for directing all ground traffic in designated "movement areas", except the traffic on runways. This includes planes, baggage trains, snowplows, grass cutters, fuel trucks, stair trucks, airline food trucks, conveyor belt vehicles and other vehicles. Ground Control will instruct these vehicles on which taxiways to use, which runway they will use (in the case of planes), where they will park, and when it is safe to cross runways. When a plane is ready to takeoff it will stop short of the runway, at which point it will be turned over to Tower Control. After a plane has landed, it will depart the runway and be returned to Ground Control.
Who instructs vehicles on which taxiways to use?

Problem: Music fans have turned to Change.org around the globe to try and block West's participation at various events. The largest unsuccessful petition has been to the Glastonbury Festival 2015 with 133,000+ voters stating they would prefer a rock band to headline. On July 20, 2015, within five days of West's announcement as the headlining artist of the closing ceremonies of the 2015 Pan American Games, Change.org user XYZ collected over 50,000 signatures for West's removal as headliner citing the headlining artist should be Canadian. In his Pan American Games Closing Ceremony performance, close to the end of his performance, West closed the show by tossing his faulty microphone in the air and walked off stage.

Problem: Norfolk Island has 174 native plants; 51 of them are endemic. At least 18 of the endemic species are rare or threatened. The Norfolk Island palm (Rhopalostylis baueri) and the smooth tree-fern (Cyathea brownii), the tallest tree-fern in the world, are common in the Norfolk Island National Park but rare elsewhere on the island. Before European colonization, most of Norfolk Island was covered with subtropical rain forest, the canopy of which was made of Araucaria heterophylla (Norfolk Island pine) in exposed areas, and the palm Rhopalostylis baueri and tree ferns Cyathea brownii and C. australis in moister protected areas. The understory was thick with lianas and ferns covering the forest floor. Only one small tract (5 km2) of rainforest remains, which was declared as the Norfolk Island National Park in 1986.
