Here is a prahelika.
You have to identify the verb(क्रियापदम्) in this sloka, with its grammatical form.
"प्रातः प्रातः समुत्थाय द्वौ मुनी कुंभमंभसा।"अत्र क्रियापदं वक्त्तुर्हैमं दास्यामि कङ्कणम्।
[It's literal meaning goes like this: "Whosoever finds out the verb in the first part of this sloka will get a bangle made of gold."
