General Science

The question refers to the patenting of a rice variety by a foreign company, even though similar varieties have been known and cultivated in India for a long time. This situation is directly related to Basmati rice.

Explanation:

• Basmati rice: Basmati is a variety of long-grain rice which is traditionally grown in India and Pakistan. It is known for its distinct aroma, flavor, and delicate texture. In the late 20th century, a U.S. company was granted a patent for a rice strain they developed, which they claimed to be similar to Basmati. This caused significant controversy because Basmati has been cultivated in India and Pakistan for hundreds of years. The patenting was seen as an example of 'biopiracy' -- where a foreign entity claimed ownership over a product or resource traditionally used by indigenous people.
• Other Options:
  • Co-667: This is not related to Basmati rice. It generally refers to sugarcane varieties.
  • Lerma Rojo: This variety is associated with wheat and does not apply to the context of rice varieties.
  • Sharbati Sonora: This is a type of wheat, not directly related to issues concerning rice varieties like Basmati.

Conclusion:

The correct answer is "Basmati" because it is the variety of rice that has been involved in international patent disputes due to its traditional presence in India.

The question asks about the celebration date of World Ozone Day. Let's analyze each option and identify the correct answer.

1. 5^th June: This date is celebrated as World Environment Day, which focuses on environmental issues at large.
2. 16^th September: This date is recognized globally as World Ozone Day, officially known as the International Day for the Preservation of the Ozone Layer. This day was designated by the United Nations General Assembly in 1994 to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987.
3. 21^st April: This date does not correspond to World Ozone Day. It is celebrated as Civil Services Day in India.
4. 22^nd April: This day is known as Earth Day, which highlights the importance of protecting our planet and its environment.

Based on the analysis above, the correct answer is:

16^th September

World Ozone Day is crucial for raising awareness about the importance of the ozone layer and the need to reduce substances that deplete it. Celebrating this day symbolizes our collective commitment to addressing climate change and protecting the earth's atmosphere.
