Given the task definition, example input & output, solve the new input case.
In this task, you are given a paper review. Based on the review, your job is to identify language and generate "en" if the review is in English or generate "es" if the review is in Spanish. Note that URLs in the text have been replaced with [Link].
Example: Este articulo no es un articulo de investigacion, ya que solo muestra como programar un robot mediante la herramienta de logica difusa. Este tema ya ha sido propuesto como solucion en navegacion de robots.
Output: es
This review is written in spanish. Hence, the label is 'es'.

New input case for you: This paper proposed an iterative query updating mechanism for cloze-style QA. The approach is novel and interesting and while it is only verified in the paper for two Cloze-style tasks (CBT and WDW), the concept of read/compose/write operations seem to be more general and can be potentially applied to other reasoning tasks beyond Cloze-style QA. Another advantage of the proposed model is to learn when to terminate the iteration by the so-called adaptive computation model, such that it avoids the issue of treating the number of iterations as another hyper-parameter, which is a common practice of iterative models/multi-hop reasoning in previous papers. There are a couple places that this paper can improve. First, I would like to see the results from CNN/Daily Mail as well to have a more comprehensive comparison. Secondly, it will be useful to visualize the entire M^q sequence over time t (not just z or the query gating) to help understand better the query regression and if it is human interpretable.
