We present a novel method for obtaining high-quality, domain-targeted multiple choice questions from crowd workers. Generating these questions can be difficult without trading away originality, relevance or diversity in the answer options. Our method addresses these problems by leveraging a large corpus of domain-specific text and a small set of existing questions. It produces model suggestions...

the present study seeks to investigate the potentiality of the translation task as a testing method for measuring reading comprehension. to achieve this objective, two types of translation tests, open-ended and multiple-choice tests, and two types of reading comprehension tests, multiple-choice reading comprehension and open-ended cloze tests were developed in this study. the reliability of the...
