Question

complete the text with the analysis that most logically connects the claim and evidence.
though astrophysicist jason steffen devised a more efficient method of boarding planes,
airlines arent likely to use it. according to steffens computer model, passengers in odd-numbered window seats should board first, followed by passengers in even-numbered
window seats. the same sequence should then be applied to middle seats and aisle
seats. while the steffen method reduces boarding time, it only saves a few minutes per
flight. furthermore, because it requires people to board in a very specific order,
passengers are likely to find the process frustrating or unnecessarily complex. the
method is particularly impractical for parents traveling with small children, since
passengers sitting in the same row cant board together. therefore, ________
ultimately, airlines will probably maintain their current boarding protocols.
passengers would likely appreciate the efficiency of the steffen method after
getting used to this unique boarding pattern.
families traveling with children would benefit from adapting to the steffen
method in order to save time.
airlines may find it beneficial to offer incentives to passengers who comply
with the steffen method.
the minimal time savings resulting from the steffen method may not justify
disrupting familiar boarding routines.

Explanation:

The text argues airlines won't adopt the Steffen Method, citing minimal time savings and passenger frustration/impracticality (especially for families). The missing sentence must logically connect these flaws to the conclusion that airlines will keep current protocols. The correct option ties the small time benefit to the cost of changing familiar routines, aligning with the preceding evidence.

Answer:

the minimal time savings resulting from the Steffen Method may not justify disrupting familiar boarding routines.
