Ans) C
Exp)
• The Aegis Ashore systems is a land-based missile defence system developed by the United States of America. Recently, Japan's National Security Council has endorsed plans to cancel the deployment of two costly Aegis Ashore systems of U.S. aimed at bolstering the country's capability against threats from North Korea.

Regarding 'Yellow rust' consider the following statements:
1. It is formed when sulfur dioxide and nitrogen oxides are emitted into the atmosphere.
2. It comes out on clothing or fingers when touched.
3. It spreads easily during the onset of cool weather and when wind conditions are favourable.
Which of the statements given above is/are correct?
Ans) B
Exp)
• Statement 1 is incorrect. Yellow rust is a disease that appears as yellow stripes of powder or dust on leaves and leaf sheaths of the wheat crop. Recently, the Punjab Agriculture and Farmers' Welfare Department issued an advisory about Yellow Rust disease in wheat crops followed by a similar advisory from the Indian Institute of Wheat and Barley Research (IIWBR) after Yellow Rust was detected in wheat crops in parts of Punjab and Haryana.
• This yellow powder comes out on clothing or fingers when touched. The disease can spread rapidly under congenial conditions and affects crop development, and eventually the yield. Hence, statements 2 and 3 are correct.

Consider the following statements:
1. The Polar Satellite Launch Vehicle (PSLV) is the first Indian launch vehicle to be equipped with liquid stages.
2. The MOM mission was carried out by it.
Which of the statements given above is/are correct?
Ans) C
Exp)
• Both the statements are correct. Polar Satellite Launch Vehicle (PSLV) is the third generation launch vehicle of India. It is the first Indian launch vehicle to be equipped with liquid stages. After its first successful launch in October 1994, PSLV emerged as the reliable and versatile workhorse launch vehicle of India with 39 consecutively successful missions by June 2017. During 1994-2017 period, the vehicle has launched 48 Indian satellites and 209 satellites for customers from abroad.
• The PSLV has four stages using solid and liquid propulsion systems alternately.
The Polar Satellite Launch Vehicle (PSLV) successfully launched two spacecraft – Chandrayaan-1 in 2008 and Mars Orbiter Spacecraft in 2013 – that later traveled to Moon and Mars respectively
1. First Generation: Satellite Launch Vehicle
2. Second Generation: Augmented Satellite Launch Vehicle (ASLV)
3. Fourth-stage Launch Vehicle: Geosynchronous Satellite Launch Vehicle (GSLV)

Regarding Hydrogen enriched CNG (H-CNG), consider the following statements:
1. It does not emit carbon monoxide.
2. It is cheaper than CNG.
3. It improves fuel efficiency.
Which of the statements given above is/are correct?
Ans) A
Exp)
• Statement 1 is incorrect. Compared to conventional CNG, use of H-CNG can reduce the emission of carbon monoxide up to 70%. H-CNG is not used worldwide yet. Trials have been held in countries such as the US, Canada, Brazil and South Korea. It is not a zero-emission technology.
• Statement 2 is incorrect. The NITI Aayog-CII Action Plan for Clean Fuel has noted that the blending of CNG and hydrogen involves a series of energy-intensive steps that would make H-CNG more expensive than CNG. Moreover, hydrogen as fuel is itself expensive.
• H-CNG is a blend of hydrogen and CNG, the ideal hydrogen concentration being 18%. The NITI Aayog has recommended the use of H-CNG as an alternative fuel. The Environment Pollution Prevention and Control Authority (EPCA) recommended to the Supreme Court that Delhi's buses switch to H-CNG within the next two or three years.
• Statement 3 is correct. H-CNG improves engine efficiency, lowers fuel consumption up to 5 per cent as compared to a CNG bus.

The National Genomic Grid aims to study genomic data of
Ans) B
Exp)
• Recently, the government has announced to set up a National Genomic Grid (NGG), which will study genomic data of cancer patients from India.
• NGG will collect samples from cancer patients, through a network of pan-India collection centres by bringing all cancer treatment institutions on board. The grid to be formed will be in line with the National Cancer Tissue Biobank (NCTB) set up at the Indian Indian Institute of Technology, Madras.
Application:
• Through the National Genomic Grid, the government seeks to boost cancer research and make treatment viable for people of different economic classes.
• NGG will help to study genomic factors influencing cancer and identifying the right treatment modalities for the Indian population.
• National Cancer Tissue Biobank (NCTB), is a joint initiative of the Department of Science and Technology (DST), Government of India and Indian Institute of Technology, Madras.
• The biobank collects cancer tissue samples with consent from patients diagnosed with cancer.
• The aim is to provide researchers with high quality of cancer tissues and the patient data in order to facilitate cancer research that will lead to improvements in cancer diagnosis and treatment.
