I want to know the answer to the following question:
What percentage of the New York City cab fleet was clean diesel or hybrid in 2010?
All the background I'm provided with is that "Also, by 2010, the city had 3,715 hybrid taxis and other clean diesel vehicles, representing around 28% of New York's taxi fleet in service, the most of any city in North America.". Is that enough to answer the question?
Answer: yes
