Why is it challenging to choose among options for solving a transportation problem?
natulia [17]

The correct answer to this open question is the following.

Unfortunately, you did not specify if you refer to a specific place, city, country, or time in history. There is no context or further reference in your question.

That is why we are going to answer in general terms.

It is challenging to choose among options for solving a transportation problem because there are too many vehicles driving in overcrowded metropolises and the current transportation system has not been efficient. Another challenge is that public transportation units are old and do not represent an attractive alternative for people to leave their vehicles at home and use the public transportation system.

Government officials should change the approach of public transportation to make it attractive and efficient, which also includes the refurbishing, reparation, or construction of new highways for public transportation. Safety is another important factor that is part of the transportation ecuation.
