What we don’t know, for example：
• Is post-editing SMT more efficient than translating from scratch?
• Is pre-editing SMT more effective than post-editing?
• Should always apply your client’s TM 100% matches?  
• Should you translate fast then revise slowly, or vice versa?
• Should you revise a translation with or without looking at the start text?  
• Should you translate into L2?
• Can you translate 30% faster without losing quality?
• Are translators able to negotiate directly with text-using clients?
