With the world’ s population estimated to grow from six to nine billion by 2050, researchers, businesses and governments are already dealing with the impact, this increase will have on everything from food and water to infrastructure(基础设施)and jobs. Underling all this【C1】______will be the demand for energy, which is expected to double over the next 40 years.

【C4】
选项
答案
O
解析
此处需填入副词,修饰空格后的动词词组being funded and developed。下文接着说的是可替代能源在世界能源供给中扮演越来越重要的角色,由此可推断资助发展可替代能源是理所当然的事情,故选Certainly。此处填入备选的另一个副词exactly(准确地,精确地)语义不通。
