Explanation:

• Option (1) is the correct answer: Digital cookies are small packets of data or code that are stored on a user’s device when they visit a website. Cookies serve as a website’s memory, recognizing users upon their return, enabling features like automatic login and maintaining items in an online shopping cart. Cookies can track a user’s online behavior, which, while often harmless, can raise concerns about digital privacy. The multitude of cookies generated by poorly optimized third party websites can lead to a data overload that may slow down web browsers, resulting in a sluggish web experience for users. Privacy regulations like the General Data Protection Regulation (GDPR) and The California Consumer Privacy Act (CCPA) require websites to obtain user consent before deploying certain types of cookies. This has led to the appearance of pop-up notifications and prompts seeking user approval, which some users find irksome.

Explanation:

• Option (4) is correct: The pink bollworm is a moth that is a major pest of cotton. The pink bollworm is native to Asia, but has become an invasive species in most of the world’s cotton-growing regions. The larvae bore into cotton bolls and feed on the seeds, destroying the cotton and reducing the yield and quality (yield losses can be as high as 50%). It can also reduce the quality of cotton by staining the lint and making it more difficult to process. It has also been observed to attack hibiscus, okra, and hollyhock plants. Features of Pink bollworm:
  • The pink bollworm is a small, grayish-brown moth with a wingspan of about 1 inch.
  • The larvae are white caterpillars with pink bands on their backs.
  • The larval stage is the destructive and identifiable stage.
  • The larvae can grow up to 1/2-inch long.

Explanation:

• Statement 1 is correct: Cotton is a water intensive crop that requires almost 75 lakh liters of water per hectare. It is cultivated in the well-drained black soil of Deccan plateau. It requires rainfall of around 50-100cm.
• Statement 2 is correct: Cotton is one of the most important cash and fibre crops in India. It is a Kharif crop that is sown from June to July and harvested from October to January. Top cotton producing states in India are Gujarat, Maharashtra, Telangana, Andhra Pradesh and Rajasthan.

Explanation:

• Statement 1 correct: The terahertz range (THR) is a region of the electromagnetic spectrum that lies between microwaves and infrared light. It has frequencies between 0.1 and 10 THz, or wavelengths between 3 mm and 30 μm.
• Statement 2 incorrect: THR has some unique properties that make it useful for a wide range of applications. It can penetrate many materials that are opaque to other types of radiation. However, it is non-ionizing, meaning that it cannot damage DNA.
• Statement 3 correct: THR is also very sensitive to the chemical composition of materials, which makes it useful for spectroscopy and imaging. Potential applications of THR are security screening, medical imaging, detecting food contamination and adulteration, industrial inspection, and high-speed wireless communication etc.

Explanation:

• Option (4) is correct: Global Innovation Index (GII) 2023 rankings have been released by the World Intellectual Property Organization (WIPO). India ranked 40th out of 132 economies in the GII 2023. It tracks the most innovative economies in the world, ranking the innovation performance of around 132 economies while highlighting innovation strengths and weaknesses. Parameters used for computing the GII include:
  • Institutions
  • Human capital and research
  • Infrastructure
  • Market sophistication
  • Business sophistication
  • Knowledge and technology outputs
  • Create outputs
