I want to know the answer to the following question:
Following what event was it uncertain if Shell would recommence drilling?
All the background I'm provided with is that "It was unclear if Shell would recommence drilling in mid-2013, following the "Kulluk" incident and, in February 2013, the corporation stated that it would "pause" its closely watched drilling project off the Alaskan coast in 2013, and will instead prepare for future exploration.". Is that enough to answer the question?
Answer: yes
