I had an English test today, which had a question like this -
The king had many occasions ________________ (experience) the power of the writing on the paper during his reign.
Just for context, here's the part just before the sentence —
Once a king asked a hermit for a powerful talisman. The hermit gave him a ring containing a folded slip of paper and asked him to open it whenever faced with an extraordinary situation, be it a tragedy or a triumph. The talisman, the hermit told the king, would keep him grounded and would help him keep his head in any situation.
And here's what's after —
The paper had on it a simple line: "This, too, shall pass."
I wonder what can be filled in the blank. Is to experience
correct? Or is it experiencing
? Or both? Please also explain why.
