I want to know the answer to the following question:
Who is Dawoodi Bohra's present 53rd Da'i al-Butlaq?
All the background I'm provided with is that "After his death, they believe their 21st Imam Taiyab abi al-Qasim went into a Dawr-e-Satr (period of concealment) that continues to this day.". Is that enough to answer the question?
Answer: no
