In plain words
Then Jaivali invited him to stay; but the boy, paying no heed to the invitation, ran away. He came to his father and said, "So thou didst tell me before that thou hadst taught me!" "How so, my clever son?" "A man of the princely class asked me five questions, and I did not know one of them." "Which were they?" "These," he said, and repeated their first words.

Bṛhadāraṇyakopaniṣadbhāṣyam· bhāṣya
राजन्या बन्धवो यस्येति ; परिभववचनमेतत् राजन्यबन्धु- रिति ; अप्राक्षीन् पृष्टवान् ; ततः तस्मात् न एकंचन एकमपि न वेद न विज्ञातवानस्मि । कतमे ते राज्ञा पृष्टाः प्रश्ना इति पित्रा उक्तः पुत्रः ‘इमे ते’ इति ह प्रतीकानि मुखानि प्रश्नानाम् उदाजहार उदाहृतवान् ॥
In plain words
'One whose kinsmen are warriors' — that's a jab, a put-down: 'you kshatriya's kinsman.' The king had questioned him, and that's exactly why: I don't know even one, I never understood a single one. 'Which questions did the king ask you?' his father demanded. So addressed, the son recited the opening lines of each question — 'here they are,' he said, laying them out one by one.
Close to the Sanskrit
'One whose kinsmen are kshatriyas' — this is an expression of contempt: 'you kshatriya's-kinsman.' He had asked him a question; therefore I do not know even one — I have not understood it. 'Which were the questions asked by the king?' Thus addressed by the father, the son recited the opening phrases of the questions, saying 'these are they' — udājahāra means 'he stated them aloud.'
