4. Which plant is cultivated for biodiesel?

Correct Answer: Correct answer is: (B) Jatropha.

Exam Relevance: GRE, GATE, NEET, JEE

Difficulty: Moderate

Concept notes: Jatropha is a plant that is cultivated for biodiesel production due to its high oil content in its seeds.

Common Mistakes: A common misunderstanding is that other oilseed crops like soya bean, sunflowers, or groundnut are the primary sources for biodiesel, when in fact, Jatropha is specifically cultivated for this purpose.

Explanations: Jatropha is a plant that is specifically cultivated for biodiesel production because its seeds contain a high amount of oil, which can be extracted and processed into biodiesel. This makes Jatropha an important source of renewable energy.

Correct Answer: Correct answer is: (A) Greenhouse gas emissions.

Exam Relevance: AP Environmental Science, GRE, GATE, MCAT

Difficulty: Moderate

Concept notes: Wind energy is a renewable resource that does not emit greenhouse gases during operation, making it an attractive alternative to fossil fuels. The primary driver for the increase in wind energy is the need to reduce greenhouse gas emissions.

Common Mistakes: A common misunderstanding is that land consumption, water consumption, or deforestation are the primary drivers for the increase in wind energy. While these factors can be relevant, the main driver is the reduction of greenhouse gas emissions.

Explanations: Wind energy is a clean and renewable source of power that does not produce greenhouse gas emissions during operation. The increase in wind energy is primarily driven by the need to reduce greenhouse gas emissions, which are a major contributor to climate change. Other factors such as land consumption, water consumption, and deforestation are secondary concerns in the context of wind energy's primary benefit of reducing emissions.
