Explanation:

Statement 1 is incorrect. ZBNF emphasizes using locally available, on-farm bio-inputs, not external ones.

Statement 2 is incorrect. ZBNF aims to minimize input costs, not eliminate them entirely.

Statement 3 is correct. Subhash Palekar is a prominent advocate for ZBNF.

Statement 4 is incorrect. While ZBNF can improve soil health and potentially yields in some cases, consistent yield increases across all crops are not scientifically proven.

Explanation - Neutrinos are electrically neutral, elementary weakly interacting subatomic particles with half-integer spin. Neutrinos are similar to the more familiar electron, with one crucial difference: neutrinos do not carry electric charge. Because neutrinos are electrically neutral, they are not affected by the electromagnetic forces which act on electrons.

Explanation - Establishment: MERCOSUR was indeed established by the Treaty of Asunción in 1991. This treaty marked the formal creation of the trade bloc. Founding Members: Venezuela is not a founding member of MERCOSUR. The original founding members are Argentina, Brazil, Paraguay, and Uruguay. Venezuela joined MERCOSUR later, in 2012, but it is not considered a founding member. Objectives: MERCOSUR aims to promote economic integration and reduce trade barriers among its member countries, which aligns with the bloc's core objectives.
