Task: Question Answering
Input (English): For the MCTest dataset, Fig. FIGREF30 compares our proposed models with the current state-of-art ensemble of hand-crafted syntactic and frame-semantic features BIBREF16 , as well as past neural models from the literature, all using attention mechanisms — the Attentive Reader of BIBREF26 , Neural Reasoner of BIBREF27 and the HABCNN model family of BIBREF17 .  
 Question: what is the state of the art for ranking mc test answers?
Output (English): ensemble of hand-crafted syntactic and frame-semantic features BIBREF16
