In India, the segregation of municipal waste at source is rare. Recycling is mostly with the informal sector. More than three-fourths of the municipal budget goes into collection and transportation, which leaves very little for processing/resource recovery and disposal. Where does waste-to-energy fit into all this ? Ideally it fits in the chain after segregation (between wet waste and the rest), collection, recycling, and before getting to the landfill. Which technology is most appropriate in converting waste to energy depends on what is in the waste (that is biodegradable versus non-biodegradable component) and its calorific value. The biodegradable component of India's municipal solid waste is a little over 50 per cent, and biomethanation offers a major solution for processing this.

Based on the above passage, the following assumptions have been made:

1. Collection, processing and segregation of municipal waste should be with government agencies.

2. Resource recovery and recycling require technological inputs that can be best handled by private sector enterprises.

Which of the assumptions given above is/are correct?

A
1 only
B
2 only
C
Both 1 and 2
D
Neither 1 nor 2

A
Generation of energy from municipal solid waste is inexpensive.
B
Biomethanation is the most ideal way of generating energy from municipal solid waste.
C
Segregation of municipal solid waste is the first step in ensuring the success of waste-to-energy plants.
D
The biodegradable component of India's municipal solid waste is not adequate to provide energy from waste efficiently/effectively.

There is a claim that organic farming is inherently safer and healthier. The reality is that because the organic farming industry is still young and not well-regulated in India, farmers and consumers, alike, are not only confused about what products are best for them, but sometimes use products in ways that could harm them as well. For example, since organic fertilizers are difficult to obtain on a large scale in India, farmers often use farmyard manure, which may contain toxic chemicals and heavy metals. Certain plant sprays, such as Datura flower and leaf spray, have an element called atropine. If it is not applied in the right dose, it can act on the nervous system of the consumer. Unfortunately, how much and when to use it are not well-researched or regulated issues.

Based on the above passage, the following assumptions have been made:

1. Organic farming is inherently unsafe for both farmers and consumers.

2. Farmers and consumers need to be educated about eco-friendly food.

Which of the assumptions given above is/are correct ?

A
1 only
B
2 only
C
Both 1 and 2
D
Neither 1 nor 2

Which one of the following statements best reflects the most logical, rational and practical message conveyed by the author of the passage?
A
In India, organic farming should not be promoted as a substitute for conventional farming.
B
There are no safe organic alternatives to chemical fertilizers.
C
In India, farmers need to be guided and helped to make their organic farming sustainable.
D
The aim of organic farming should not be to generate huge profits as there is still no global market for its products.
