Clauses starting with Who, Which, Whose, Where, When to describe a noun.

🔒 Restrictive (Defining)

Essential info. No commas.

"The student who studies hard succeeds."

If we remove it ("The student succeeds"), we don't know WHICH student.

🔓 Non-Restrictive (Non-Defining)

Extra info. Uses commas.

"My father, who is a doctor, lives here."

If we remove it, we still know who "My father" is.

Never use 'That' in Non-Restrictive clauses!

Pronoun Use Example
Who People The man who called...
Which Things/Animals The car which crashed...
Whose Possession The boy whose dad is famous...
Where Place The city where I live...

4. Writing: Expository Essay

Task: Explain the causes and effects of Brain Drain.

Brain Drain: A Threat to Development

Brain drain is a major issue facing developing countries. It refers to the mass emigration of skilled professionals to developed nations. This phenomenon has several causes and serious effects.

There are two main causes: push and pull factors. Push factors include low wages and unemployment in the home country. Professionals feel undervalued. Pull factors, like high salaries and better labs abroad, attract them to leave.

Consequently, the effects are damaging. The home country loses its human capital, which slows down economic growth. Hospitals lose doctors, and schools lose teachers.

In conclusion, although migration is a personal choice, governments must improve conditions to keep their talents at home.
