Which of these was a factor in the u. s. entry in world war 1

You didn't list any factors, but there were many.

For instance, the USA entered World War I because Germany had sunk a ship with US passengers, the Lusitania, after an agreement that neither would attack in the sea warzone.

Another factor that caused the USA to enter World War I was the Zimmerman Telegram, Germany sent a coded telegram to Mexico in hopes of getting Mexico to ally with them and turn against the USA.

Hope this helps!

Urban growth invariably feeds increased commercialization and industrialization. it requires continually expanding land areas. when urbanization rates are high, and countries do not have the institutional and managerial capacities or economic wherewithal to manage such rapid growths, they exert intense pressure on the types and nature of the resulting settlements. they contribute to the development of overcrowded slums and shanty towns without adequate essential services and necessary infrastructure.-by asit k. biswas and cecilia tortajada
