Figure 4
The figure is divided into three dashed boxes labeled “Test paper tag”, “Question type tag”, and “C L K area tag”, showing how exam questions are categorized. On the left, under “Test paper tag”, the top half states “1100 questions from 11 test papers of first‑level P C E Q E” above a four-by-three grid of document icons captioned with years: “2014”, “2015”, “2016”, “2017”, “2018”, “2019”, “2020”, “2021”, “2022”, “2022 asterisk”, and “2023”. The bottom half reads “1040 questions from 13 test papers of second‑level P C E Q E” above another grid of document icons labeled “2014”, “2015”, “2016”, “2017”, “2018”, “2019”, “2020”, “2020 asterisk”, “2021”, “2021 asterisk”, “2022”, “2022 asterisk”, and “2023”. Arrows from both groups point to the central box. The middle “Question type tag” box contains four stacked cylindrical icons. For the first‑level questions, the upper cylinder is labeled “770 multiple‑choice single‑answer questions (M S Q s)” and the second cylinder “330 multiple‑choice multiple‑answer questions (M M Q s)”. For the second‑level questions, the third cylinder is labeled “780 M S Q s” and the bottom cylinder “260 M M Q s”. A right‑pointing arrow from this box leads to the third box. The rightmost “C L K area tag” box lists how questions are distributed across eight construction‑law knowledge areas: “457 C 1‑related questions”, “120 C 2‑related questions”, “304 C 3‑related questions”, “397 C 4‑related questions”, “130 C 5‑related questions”, “261 C 6‑related questions”, “244 C 7‑related questions”, and “227 C 8‑related questions”.The CLQA dataset.
