Task: Question Answering
Input (English): We built a phrase-based Chinese-to-English SMT system by using Moses BIBREF18 .  In the end, the final parallel text consists of around 8.8M sentence pairs, 228M Chinese tokens, and 254M English tokens (a token can be a word or punctuation symbol).  The total number of words in these two corpora is 1.81M for Chinese and 2.03M for English. 
 Question: Did they only experiment with one language pair?
Output (English): Yes
