I want to know the answer to the following question:
All taxis in Delhi were ordered to switch to what type of fuel by March 1, 2016?
All the background I'm provided with is that "Among the measures, the court ordered to stop registrations of diesel cars and sport utility vehicles with an engine capacity of 2,000 cc and over until March 31, 2016.". Is that enough to answer the question?
Answer: no
