Vizag data centre is a major challenge

In Andhra Pradesh, drones were banned from spraying fertilizers, however, it is practised in many parts of the world. In Peru, a crater was inspected with the help of drones. It has also been used for collecting water samples from aquatic animals to get their DNA data. All three functions mentioned have been performed in different parts of the world.

Statement 1 is incorrect. The production of algae-based biofuels is not limited to seas only. It can be done on land, saline water, or wastewater. Statement 2 is correct. Setting up and engineering the algae-based biofuel production does require a high level of expertise/technology, which might be a limitation for developing countries. Statement 3 is also correct. Economically viable production of algae-based biofuels does necessitate the setting up of large-scale facilities, which may raise ecological and social concerns.

Statement 1 is incorrect: Nanoparticles can exist in nature (natural nanoparticles). Volcanic eruptions, forest fires, and natural weathering processes can all create nanoparticles. Statement 2 is correct: Some cosmetics incorporate nanoparticles of ingredients like zinc oxide or titanium dioxide for sun protection or other purposes. Statement 3 is also correct: The safety of nanoparticles in consumer products is a complex issue and a growing area of research. Some nanoparticles might pose potential health or environmental risks depending on their specific properties and how they interact with the body or the environment.

* Bisphenol A (BPA) is a key component in the manufacture of polycarbonate plastics. * Polycarbonate plastics are a type of synthetic plastic material that is known to contain Bisphenol A (BPA) as a structural component. * BPA is used in the production of polycarbonate plastics, which are commonly used in various consumer products such as Water bottles, Food storage containers, Household electronics, Eyeglass lenses, Compact discs (CDs) and digital versatile discs (DVDs) * BPA has raised health concerns due to its potential to act as an endocrine disruptor, which can interfere with the body's hormonal system.

The Genetic Engineering Appraisal Committee (GEAC) is the apex body constituted in the Ministry of Environment and Forests under Rules for Manufacture, Use, Import, Export and Storage of Hazardous Microorganisms/Genetically Engineered Organisms or Cells 1989, under the Environment Protection Act, 1986. - The GEAC is responsible for the appraisal of proposals involving the release of genetically engineered organisms and products into the environment including experimental field trials.

* Statement 1 is not correct: The formation of India’s own internet companies, similar to China’s approach, is not an aim of the Digital India programme. The initiative focuses on creating digital infrastructure, providing digital services, and promoting digital literacy — not establishing government-backed internet firms. * Statement 2 is not correct: The Digital India plan does not include any policy framework to attract foreign multinational corporations to build data centres in India. While data localisation and data centre policies have emerged later under different frameworks, they are not part of the original Digital India objectives. * Statement 3 is correct: One of the key aims of Digital India is to connect villages through broadband and to provide Wi-Fi access in schools, public places, and tourist centres. This is part of its core pillars like Broadband Highways, Public Internet Access Programme, and Early Harvest Programmes.

Statement 1 is incorrect: The Smart India Hackathon (SIH) is not a scheme for developing Smart Cities. Instead, it is a nationwide initiative aimed at identifying innovative digital technology solutions to solve real-world challenges across various sectors. Statement 2 is correct: The Government of India launched the Smart India Hackathon to encourage students and professionals to develop innovative digital solutions for challenges in agriculture, health, education, energy, environment, and other domains. It serves as a platform for young minds to engage in problem-solving and contribute to technological advancements. Statement 3 is incorrect: While the hackathon focuses on digital technology innovations, it is not specifically centered on digital financial transactions. Instead, it covers a wide range of sectors where technology can drive efficiency and innovation. Hence, correct answer is option (B).

Statement 1 is correct: DigiLocker is a cloud-based digital locker system launched by the Government of India under the Digital India Programme. Its primary objective is to reduce reliance on physical documents by providing secure digital storage and access to e-documents issued by government departments, educational institutions, and other entities. Statement 2 is correct: DigiLocker enables users to access their electronic documents (e-documents) anytime, anywhere, provided they have an internet connection. This enhances convenience, eliminates the need to carry physical documents, and ensures secure and verifiable digital storage. Therefore, both statements are correct.

Majorana 1 chip is linked to quantum computing and deep learning is part of machine learning, but AWS did not introduce the Majorana 1 chip. * ✅ I. Majorana 1 chip – Expected to advance quantum computing. * ❌ II. AWS introducing Majorana 1 – Incorrect, it’s a Microsoft project. * ✅III. Deep learning – A subset of machine learning. Only statements I and III are correct.

Metaverse: This term accurately describes a network of interconnected, persistent 3D virtual spaces.  Key characteristics of the metaverse often include: * Interoperability: Users can move between different virtual worlds seamlessly. * User-Generated Content: Users can create, own, and trade virtual assets. * Social Interaction: The metaverse facilitates social experiences and interactions. _Let's look at why the other options are incorrect:_ * Big data analytics: This involves analyzing large and complex datasets to uncover patterns and insights. It's not directly related to virtual worlds. * Cryptography: This focuses on secure communication and data protection techniques. While relevant to security within a metaverse, it doesn't define the concept itself. * Virtual matrix: This term is not commonly used to describe the concept outlined in the question. The term 'matrix' is often associated with a grid-like structure or a virtual reality environment, but not the broader interconnected network the question describes.
