Analyze the following sophisticated statements regarding PBAT (Polybutylene Adipate Terephthalate) and sustainable plastic alternatives:

1. PBAT's copolymer composition of adipic acid, 1,4-butanediol, and terephthalic acid enables 100% compostability within 180 days under industrial conditions, while maintaining flexibility and toughness superior to PLA's rigid characteristics.
2. Kamalpur Nagar Panchayat's adoption of PBAT-based compostable bags in Tripura represents a strategic shift toward sustainable alternatives, with PBAT demonstrating faster composting rates compared to PLA despite higher costs than conventional plastics.
3. PBAT's moisture resistance, chemical inertness, and barrier properties, combined with its compatibility with conventional plastic manufacturing methods, position it as an optimal substitute for single-use plastics in packaging applications.

Which of the above statements demonstrates the most comprehensive understanding of PBAT's technological and economic implications?

Consider the following intricate aspects of Germany's Mixed-Member Proportional Representation electoral system:

1. The Zweitstimme (second vote) for party lists in each Länder under proportional representation determines the overall composition of the Bundestag, while the Erststimme (first vote) fills 299 constituency seats through first-past-the-post methodology.
2. Overhang seats occur when a party's first-vote victories exceed their proportional entitlement, necessitating the allocation of balance seats to other parties to maintain proportional representation integrity.
3. The Federal President's nomination of Chancellor candidates requires subsequent Bundestag approval through secret ballot, with absolute majority requirements in initial rounds and plurality sufficiency in final rounds if necessary.

Which of the above statements is/are correct?

Analyze the following complex statements regarding Titan's atmospheric dynamics and the NASA-Webb-Keck collaborative observations:

1. The convective cloud activity observed in Titan's northern hemisphere during November 2022 and July 2023 represents the first confirmed evidence of such phenomena in regions where major hydrocarbon seas like Kraken Mare and Ligeia Mare are predominantly located.
2. Titan's methane cycle complexity parallels Earth's hydrological cycle, with the observed cloud altitude variations indicating convection-driven weather patterns analogous to terrestrial atmospheric dynamics but utilizing methane and ethane instead of water vapor.
3. The Keck Observatory's dual 10-meter telescope system employs 36 hexagonal segments per primary mirror, utilizing stressed mirror polishing techniques and computer-controlled actuators to maintain hyperboloid precision for ultra-precise astronomical observations.

Which of the above statements is/are correct?

Regarding the Irula tribe's traditional practices and contemporary challenges, which of the following statements demonstrates the most accurate understanding of their socio-economic dynamics?

Regarding the Supreme Court's reinstatement of the three-year minimum practice requirement for judicial services, consider the following statements:

1. The requirement was originally proposed by the 14th Law Commission Report in 1958 and was subsequently abolished following recommendations of the Justice Shetty Commission in 2002.
2. The new directive mandates certification by senior advocates with minimum 10 years of experience and considers law clerk experience as valid practice.
3. The decision was primarily motivated by successful experiences with fresh graduate recruitment in subordinate judiciary positions across various High Courts.
