i wonder why they created tests for students like us when they are just cutting down all those innocent tress that are grown beautifully and amazingly when they shelter us from sunlight and rain. deforestation have been getting serious and serious now and the ozone layer have been tearing and tearing and soon it would be really hot in singapore and we're be sweating like how the tap water flows and we would eventually die of too much heat we faced oh no. :-(
