Checklist AICC 2025 Round 2 · Task 1
Essay Gap
Choose which of four candidate sentences correctly fills a gap in the middle of an essay.
The task
Each essay has a missing sentence in the middle. Given the text before and after the gap and four candidate sentences, the contestant must identify the option that best completes the gap, which tests understanding of textual coherence, context and semantic relations between sentences. The overview frames this as completing a page of Santa's storybook.
The training file gives the text before and after the gap, the four options and the index of the correct option; the test file gives the same fields without the label.
Contestants predict the correct option index (0–3) for each test essay.
