Cultural Tip
In everyday French, "ça" is preferred over the more formal "cela". However, in written or formal speech, swapping "ça" for "cela" can make the sentence sound more polished. Also, remember that "Qu'est‑ce qui" always introduces a subject question; using "Qu'est‑ce que" would be grammatically incorrect here.
