What kind of audio materials are presented in the DLAB?

The correct answer is that the DLAB presents phrases and sentences spoken in a made-up language. This approach is strategically designed to assess a test-taker's ability to recognize and understand complex linguistic structures that may not be familiar. By using a constructed language, the test effectively isolates language-learning aptitude from any prior knowledge of a specific language, allowing for a fair evaluation of one’s ability to grasp new linguistic patterns and sounds.

This method is indicative of how real-world language acquisition occurs, as learners often encounter unfamiliar grammar and vocabulary in the languages they study. The focus on made-up phrases and sentences challenges test-takers to apply analytical and deductive reasoning skills, essential for mastering a new language. Therefore, this choice aligns directly with the primary goal of assessing language aptitude.
