1. There are advantages and disadvantages to establishing a new university, which is close proximity to our community.

2. If the university can accommodate five thousand students, some of whom take a taxi, get a bus or ride their own motorcycle, these modes of transportation will not only increase the traffic congestion but also release a great amount of exhaust composed of some toxic substances.

3. Students, who drive cars to the university, will have to spend a great deal of time to look for a place to park. It can be waste of their time.

4. A business center at a university helps our country’s various industries to create many job opportunities.

5.Expers at the business center know what can be invested in specific areas. A large shopping center, for example, can be built in Taipei County because residents living in there have to travel long distances to buy things.

6. A business center at a university helps to rebuild up a strong foundation of our economy.

I'll take on the first two, kk.

1. There are advantages and disadvantages to establishing a new university in close proximity to our community.

2. If the university can accommodate five thousand students, many of whom will take taxis, catch buses, drive their own cars, or ride their own motorcycles, we can expect an increase in traffic congestion with its consequent release of greater amounts of toxic exhaust fumes.

Hi Rishonly,

I'm not a grammarian, but I submit that 'many of whom' retains the necessarily subordinate nature of the clause, and 'many of them' does not.
