Question

correct the text by inserting two commas. (note: in this skill, serial commas are not optional.)
,
in 1960, almost three - quarters of agadir morocco was destroyed by an earthquake and its powerful aftershocks.

Explanation:

To correct the text, we need to set off the city and country properly. "Agadir" is a city, "Morocco" is the country, so we insert a comma after "Agadir" to separate them. Also, we need another comma to separate the main clause from the phrase? Wait, no, let's re - examine. The correct placement is: "In 1960, almost three - quarters of Agadir, Morocco, was destroyed by an earthquake and its powerful aftershocks." We insert commas after "Agadir" (to set off the city from the country) and after "Morocco" (to properly structure the phrase "of Agadir, Morocco" as an appositive - like phrase giving location details).

Answer:

In 1960, almost three - quarters of Agadir, Morocco, was destroyed by an earthquake and its powerful aftershocks.
