What is the difference between "make a case for" and "present the case for"? In Chapter 33 English Collocations in Use Intermediate, the author give each collocation an example(but doesn't explain its meaning) as follow:
This makes a case for re-examining the assassination of President Kennedy in the light of evidence which has emerged since 1963.
The book The Eye of the Universe draws an analogy between the birth of the universe and a lottery. It also draws parallels between the formation of new stars and the birth and death of flowers. It presents the case for a complete rethinking of how we understand space. The author, Patrick Rivaux, puts forward the argument that the universe is as it is because we humans are here looking at it. The author takes up/adopts the position that the universe cannot have any beginning or end, and states his opinion that we can never understand the universe using the human ideas of time and space. He argues convincingly that the universe has a unique nature. He draws attention to new research which suggests that other universes may also exist alongside ours. He briefly summarises the views of leading physicists and mathematicians, disagrees profoundly with some of them and draws the conclusion that science alone cannot solve the mystery of the universe.
In this exercise section the author use make a case over present the case.
Kerr takes up a controversial position in his latest article. He puts forward the argument that differences in behaviour between the sexes can be explained totally by the genes. He attempts to make a case for educating boys and girls separately in their primary school years. He argues, occasionally convincingly, that both sexes would benefit from this. He draws attention to recent research which, he claims, lends support to his argument. However, he fails to take a number of important factors into consideration. He also makes no reference to the important work of Potter and Sinclair in this field. I am sure that I will not be alone in disagreeing profoundly with many of his conclusions.
I searched the meaning of "make a case" and found several meaning such as to explain why something should be done or is the best thing to do. But I can't find any meaning of "present the case for" on the internet.
