In a KWLQ chart, you typically write in the K (What I Know) and W (What I Want to Know) columns before reading. During and after reading, you would fill in the L (What I Learned) column. The Q (Questions) column can be used throughout the reading process to note down any questions that arise.
So, during your reading, you primarily write in the L column.
Therefore, if you're focusing on what to write during the reading phase, the correct answer is W and L (as you may still have questions during reading). However, focused writing for post-reading specifically influences the "L" column the most.
If the question allows for a focus on initial setup versus actual reading, it can be ambiguous without context. Considering typical interpretations, I'd recommend W and L.
