Given the taxi instructions "Taxi to Runway 30 via Lima and hold short of Runway 25L," what is your taxi route?

Answer: A — Requires crossing of Runway 25L at Lima.

The correct answer highlights that the given taxi instructions require crossing Runway 25L at the taxiway Lima, which is a part of the specified route. The phrase "hold short of Runway 25L" indicates that the aircraft must reach the designated hold short line without actually entering the active runway itself. As a result, this instruction implies a crossing of Runway 25L as the aircraft maneuvers according to the authorized taxiway routing before stopping at the hold short point. The other choices do not align with the taxi instructions given. For instance, the option involving "transiting HS 4" suggests a specific holding position that is not referenced in the original instruction. Similarly, crossing Runway 34R does not pertain to the route toward Runway 30 as outlined in the instructions. The mention of only taxiing along designated taxiways also does not accurately capture the necessity of crossing Runway 25L, which is integral to the taxi route as stated. Thus, the focus on crossing Runway 25L at Lima is a crucial element of this instruction.
