Task: Question Generation
Input (English): A Reservation Against Cancellation (RAC) is a type of ticket that can be sold for travel on the Indian Railways. Although it ensures certainty of travel, it does not guarantee a berth. A berth will be allocated to the person who reserves an RAC ticket if passengers who already have a confirmed ticket do not turn up before the train departure or get their confirmed ticket cancelled. A berth is split into 2 seats for 2 RAC ticket holders. If there's any last minute cancellations, or if any quota allocations remain unsold, or if any confirmed ticket holders are given a free upgrade (more later), an RAC ticket holder is given the empty berth, the other RAC ticket holder can then convert the 2 seats into a berth.
Output (English): can you board a train with rac ticket?
