a. 4

b. 5

c. 6

d. 7

ANSWER: 4

Explanation:

Chinese capital city Beijing will implement the new strictest vehicle emission standards to reduce hazardous hydrocarbon emissions by 5 percent. Beijing took the lead in China in using unleaded gasoline 2007 and worked out the Beijing II gasoline standard in 2014

Beijing also issued and implemented Beijing III, IV and V in 2005, 2008, and 2012

Gasoline standards in Beijing are always one to two stages ahead of other Chinese cities

Newest standards in Beijing were two or there stages ahead of other Chinese cities

The newest standard Beijing VI will reduce vehicle hydrocarbon emissions by 5 percent.

Beijing is expected to implement the new standard in December next year- the new strictest standard will lower emissions by 40 to 50 percent
