Review for NeurIPS paper: Generating Correct Answers for Progressive Matrices Intelligence Tests

I have read the reviews and the author response and I have also asked an expert AC to also provide a comment in lieu of a 4th reviewer (pasted below for reference). Taken all these together I will recommend acceptance, with a note. NOTE TO AUTHORS: This work is going to be the reference paper for using generation as opposed to discrimination. As such, it is really crucial to set the right path for evaluating model in a fair and rigorous way, so that research that follows on builds on a solid base. The presented evaluation has some issues (see points bellow).
