Theory led to the development of the theory of plate tectonics. a.continental driftb. thermodynamicc. seafloor spreading

The theory is A. continental drift.

The lithosphere which is the outermost layer of the planet is broken into pieces called tectonic plates. In this scientific theory called plate tectonics, seven large and greater number of small plates are broken and moved separately. This theory is based on the concept of continental drift.  

In the geologic time, continents shift their position from the earth's surface. Similar fossils found on different continent's shores prove us that the continental drift is nothing but truth.

i don't know that i agree with that but what's the question ?

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
