Quote:
“Who are Smarter- Boys or Girls?”


That should be "Who is smarter: boys or girls?" You are, in a sense, comparing two things, so use is.


It is a quote .And I think he/she used it to trigger the readers attention and I like this kind of technique.




Quote:
A worldwide controversy is the notion of who are smarter boys or girls .Some people claims that boys are smarter than girls are in every aspect of life while others argue that girls are more intelligent than boys .Every type of those supports his point of view..


A controversy and a notion are two different things. (Use about or over with controversy.)

I think a controversy is an idea or a notion. However, I have to admit that the sentence you suggested is better that mine.







Quote:
Boys are smarter because they are physically stronger, the first group maintains. Their bodies are capable of bearing hard works; such as building .It is very difficult for women to build a house under the hot beams of the sun .This, in turn, qualify boys to be more intelligent because they will have more experience and they will learn a great deal from it.


The first sentence is fine (although the argument is dubious).

The second sentence is a mess. You have somehow managed to separate them from their bodies. (No mean feat!) What you mean to say is that males are stronger and have more endurance than females. ( I MEAN THAT MALES HAVE MORE PHSYCAL ENDURANCE THAN FEMALES .)

They (males) can lift heavier loads and can work harder longer. The third sentence seem to be making the argument that men find it very easy to build a house in the hot sun. Grammatically, the last sentence is perfectly fine, but to say that something qualifies somebody to be intelligent is to say something nonsensical. You can't be qualified to be intelligent. Intelligence is itself a quality.
What I meant is that they will learn a lot because they will witness and experience things that the females do have the opportunity to learn. Consequently, if we get an experienced male and an inexperienced female ( as it is common in my country ) to build a house who do you think will be able to perform better ?




What research? What nerve? Is that "nerve theory" consistent with what is known about brain anatomy?
Well, I have read this in an article titled “Scientists Probe the Roots of Abilities That Seem Linked t Sex “ and

many scientists believe this to be true.




I see opinions but nothing to back them up. You suggest that women are not goal-oriented and are not good at solving problems, but you offer no evidence to support that assertion.



I HAVE GIVEN MY OPINION AND THAT CAN BE CONSIDERED AS A PERSONAL EXPERIENCE BY WHICH I SUPPORT MY ARGUMENT WITH.
Do you have any suggestions about other techniques I can use or examples to boost my argument?
