Vp Classes answered • 4 hours ago |
Option B is the correct answer because the passage clearly states that the main theme of the 9th World Convention on Recycling and Waste Management is "Advocating Waste Disposal and Recycling Practices for Clean and Green Environment". This is mentioned in the second paragraph of the passage.
The passage also states that the conference will provide a platform for leading scientists, researchers, and scholars from around the world to present their research related to the theme of the conference. Additionally, young researchers and students will have the opportunity to present their research through oral presentations, which can lead to collaboration among young researchers.
Therefore, the theme of the conference is focused on promoting waste disposal and recycling practices for a cleaner and greener environment, and the conference aims to bring together researchers, scientists, and scholars to present their research related to this topic.

The formula for finding the sum of interior angles of a polygon is:
Sum of angles = (n-2) � 180�
where n is the number of sides of the polygon.
In this case, the sum of angles is given as 1080�. We can set up the equation:
1080� = (n-2) � 180�
Now we need to solve for n:
1080� = 180�n - 360�
Add 360� to both sides:
