Writing assignment: "contrast"

This is my article that I wrote in a class last week.

▼The difference between living in a suburb and downtown.

Generally speaking, there are the two ways of living according to a resident's needs.
  I'd like to look at some differences between them. The first is about loudness.  As you know, it is always crowded downtown, so if noise is an issue, I advise you not to move there. On the other hand, a suburb is more or less quiet, except around the station.
The second difference is the convenience. Downtown, there are a variety of shops, from specialty shops to convenience stores.

When shopping for daily necessities, you are sure to find what you need, because everything is within walking distance.
Shopping in the suburbs is less convenient, because people usually live further away. To make matters worse, most shops in the suburbs close before night fall dusk.
The third difference is the cost between the two. If you live in the city, it is more expensive, simply because of the convenience of the location.

The third difference is about costs. If you want to live in the center of a city, you'll be surprised to know how expensive it costs you is to live even if you live in a far smaller than a room than you live in now because of its conveniently location and popularity.
That is to say, it's difficult for those who can't afford to pay to live near a downtown.
On the other hand, a city dweller can't believe other province's rent the rent in other places. Probably, especially for those who don't do so, living in a suburb is to theirs benefit to some extent.
In conclusion, because each of these ways has its merits and demerits, people can choose a suburb or a downtown depending on their situations and elements that they set a high value on.

Dealing With Website Hackers

Last weekend, one of the most famous websites in Brazil was attacked by hackers, and nobody could access it. I think it´s happened because of the rape in Brazil. <em>(MY COMMENT: I'm confused... was there a famous rape recently in Brazil?)</em>  This is a way to for someone to protest against to the politicians and Brazilian’s problems.

When one website is attacked, the hackers get access to the server and embed some malicious code to revoke the site's access or to redirect to their own website. Therefore, the security has to be improving improved by encrypting the database and patching any vulnerabilities though to prevent another problem.

I think this website will never be attacked by hackers again, at least until some creative hacker comes up with a new way to wreak havoc. Therefore, the other's government's websites are not free immune from them.
