WPI tracks inflation at the producer level and CPI captures changes in prices levels at the consumer level. WPI does not capture changes in the prices of services, which CPI does. In WPI, more weightage is given to manufactured goods, while in CPI, more weightage is given to food items.
The Office of Economic Adviser, Ministry of Commerce and Industry, publishes WPI data, whereas the National Statistical Office (NSO), Ministry of Statistics and Programme Implementation, publishes CPI data (MoSPI). (Statements 2 and 3 are incorrect)

It is a chemical compound which is also known as nitro chloroform. It is used both as a warfare agent and pesticide.
It is a colourless to yellow oily liquid. It is used broadly as a fungicide, herbicide, insecticide, nematicide and antimicrobial. It is an irritant with characteristics of a tear gas. It has an intensely irritating odour, and can be absorbed through inhalation, ingestion, and the skin.
It was first made for use as a poison gas in the First World War, by both the Allied and the Central Powers.
It’s manufactured in a chemical reaction involving sodium hypochlorite (which in dilute form is called bleach) and nitromethane (a common industrial solvent).
It can also be made by combining chloroform with nitric acid, which yields chloropicrin and water.
Chloropicrin has documented irritating and tears-inducing effects on humans, and is also known to be highly toxic and carcinogenic and also induce vomiting.

(b) 2 Only
Carbon farming is a set of agricultural practices that aim to store carbon in the soil, plant material, wood, and leaves.
The goal of carbon farming is to reduce the amount of carbon dioxide (CO2) and other greenhouse gases in the atmosphere, which can help mitigate climate change.
In regions with adequate rainfall and fertile soil, the potential for carbon sequestration through practices like agroforestry and conservation agriculture may be particularly high.
On the other hand, carbon farming can be challenging in hot and dry areas where the availability of water is limited. (Statement 2 is incorrect)
Limited water availability can hinder the growth of plants, thus restricting the potential for sequestration through photosynthesis.
E.g., practices like cover cropping, which require additional vegetation between main crop cycles, may not be viable due to the added water demand.

(d) Confederation of Indian Industry (CII)
The CII has introduced a Corporate Governance Charter specifically for startups, focusing on principles such as Transparency and Fairness. This charter aims to help startups achieve stability and success by addressing governance issues that have been highlighted in cases involving companies like BharatPe and GoMechanic.

India has allowed the export of 99,150 tonnes of onions to several countries, including Bangladesh, UAE, Bhutan, Bahrain, Mauritius, and Sri Lanka, despite a ban on onion exports. Additionally, 2,000 tonnes of white onions are permitted for markets in the Middle East and Europe. The National Cooperative Exports Limited (NCEL) manages these exports, mainly sourced from Maharashtra. The export ban was implemented on December 8, 2023, due to lower crop estimates, and trade matters are overseen by the Directorate General of Foreign Trade. The target for onion buffer procurement in 2024 is 5 lakh tonnes.
