Hebrewחזר בשאלהWhen an orthodox jew becomes less orthodox / non-jewish.

The term "חזר בתשובה" (literal translation: 'returned with an answer') is an idiom for someone who became religious / more religious (e.g a Hiloni jew becoming Haredi). (the 'answer' in the idiom is god / judaism) the idiom 'חזר בשאלה' means the exact opposite (שאלה = question)- someone becoming less devout/religious: for example a Dati jew renouncing his faith.
