Cooperation will benefit the society
Use “society” and not “the society” when referring to society in general / the world in general. When you use the definite article (“the”), you are referring to a specific society (eg. Singapore) which is often not the case. This incorrect use of “the” is very common and should be duly noted.

As you have already used “they” as the subject of your sentence, you do not have to use “they” after “and”.
Technological advancement has led to a lot of benefits, for example cure illnesses..
Start a new sentence with subject, verb and object – “For example, illnesses have been..”. This is a classic case of the run-on sentence – connecting a new clause to a previous clause when you really should be starting a new sentence.
Lewis Hamilton won the Singapore Grand Prix, he is a deserving winner.
Another run-on sentence that can be corrected by the use of the semi-colon (Lewis Hamilton won the Singapore Grand Prix; he is a deserving winner). Alternatively, start a new sentence OR use a conjunction (“and”).
For instance, Fernando Alonso.
Firstly, social aspects.
These are fragments and not proper sentences. Proper sentences have at least a subject (Fernando Alonso) and a verb (finished… third).
