What is carbon capture and storage (ccs)?
1 a process to further limit carbon dioxide emissions from burning coal
2 a process using high pressure to obtain hydrocarbons from shale rock
3 a method for storing fossil fuels that prevents leakage into the environment
4 a new technology for mining coal that reduces the amount of coal dust produced

The correct answer is "1".

Carbon Capture and Storage is a process of capturing carbon dioxide from a source, then transporting it to a storage site where it will not enter the atmosphere. Sources of Carbon Dioxide include carbon, petroleum, and biomass. The purpose is to mitigate Carbon Dioxide emissions from large industrial producers that could potentially unbalance the percentage of the component in the atmosphere, causing hazardous consequences on people.

true true true true that all

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
