Current Affairs for IAS Prelims 2017: Science and Technology Quiz III

Nov 24, 2016 14:59 IST

    IAS aspirants should go through various sets of multiple choice questions of science and technology because it will ensure better level of their preparation for IAS Prelims Exam 2017. Here, we have created useful questions for IAS Prelims Exam, go through it.

    1. Consider the following statements regarding Pneumonia and Diarrhoea Progress Report published annually by the International Vaccine Access Centre (IVAC):
    I. India has recently announced a partial introduction of the vaccine in five states (Bihar, Uttar Pradesh, Rajasthan and Madhya Pradesh and Himachal Pradesh) from 2017.
    II. Nearly 15 years after the introduction of the pneumococcal conjugate vaccines in 2000, five countries among those with the highest pneumonia burden — India, Indonesia, Chad, China and Somalia — are still not using the vaccine in their routine immunisation programmes.
    III. As per the report, India is among the 12 nations that have improved their Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea (GAPPD) score this year.

    Which of the following statement(s) is/are correct?
    a. Only I
    b. I and II
    c. I and III
    d. All of the above

    Answer: d

    Explanation:

    November 12 of every year marked as the World Pneumonia Day and this year India stands pretty much where it stood last year — right on top of the charts with a total of 2,96,279 deaths from pneumonia and diarrhoea, the tally being just short of last year’s figure of 2,97,114 deaths, and the nation desperately needs to reduce those numbers.

    The report, however, does indicate some consolation can be found in the fact that India is among the 12 nations that have improved their Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea (GAPPD) score this year. India recently announced a partial introduction of the vaccine in five states (Bihar, Uttar Pradesh, Rajasthan and Madhya Pradesh and Himachal Pradesh) from 2017.

    2. Which of the following pythogens has been found in the liver and gut of poultry birds and is believed to co-evolve with its natural host, when consumed, are known to cause gastrointestinal infections in humans?
    a. Trypanosoma cruzi
    b. Helicobacter pullorum
    c. Haemophilus ducreyi
    d. Streptococcus pyogenes

    Answer: b

    Explanation:

    In a first evidence of multidrug resistance in poultry sold in Indian markets, researchers in Hyderabad have isolated a bacterium in chicken that may well be the source of transmission of the drug-resistant pathogen to humans.

    The pathogen, called Helicobacter pullorum, was found in broiler and free-range chickens from markets in the city, which— besides being untreatable— could also, are cancer-causing.

    H. pullorum is commonly found in the liver and gut of poultry birds and is believed to co-evolve with its natural host. Infected chicken, when consumed, are known to cause gastrointestinal infections in humans. The study by the Hyderabad researchers, published on November 4 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology, is the first data on prevalence and isolation of H. pullorum in India.

    3. Consider the following statements regarding India’s successful test-fire of  indigenously developed nuclear capable Prithvi-II missile recently:
    I. India today on November 21, 2016 has successfully test-fired it’s indigenously developed nuclear capable Prithvi-II missile twice in quick succession as part of a user trial by the army from a test range at Chandipur in Odisha.
    II. The two surface-to-surface missiles which have a strike range of 350 km and are capable of carrying 500 kg to 1,000 kg of warheads were successfully test-fired in quick succession from mobile launcher from launch complex-3 of the Integrated Test Range (ITR)
    III. Prithvi-II is the first missile to be developed by the DRDO under the Integrated Guided Missile Development Programme.

    Which of the following statement(s) is/are correct?
    a. Only I
    b. I and II
    c. I and III
    d. All of the above

    Answer: d

    Explanation:

    India has successfully test-fired its indigenously developed nuclear capable Prithvi-II missile twice in quick succession recently as a part of user trial by the army from a test range at Chandipur in Odisha.

    In salvo mode, the two surface-to-surface missiles which have a strike range of 350 km and are capable of carrying 500 kg to 1,000 kg of warheads were successfully test-fired in quick succession from mobile launcher from launch complex-3 of the Integrated Test Range (ITR) at around 9.35 am. Inducted into Indian armed forces in 2003, the nine-metre-tall, single-stage liquid-fuelled Prithvi-II is the first missile to be developed by the DRDO under the Integrated Guided Missile Development Programme.

    4. The Indian Navy has recently inducted four SONAR systems to boosts its underwater surveillance capabilities. Which of the following is not one of those four systems?
    a. ABHAY
    b. HUMSA-UG
    c. AIDSS
    d. PACS

    Answer: d

    Explanation:

    Four types of indigenously developed SONAR systems recently have been inducted by Indian Army into its inventory. The sonar systems are capable of strengthening the Navy’s underwater surveillance capabilities. The systems have been designed and developed by Naval Physical & Oceanographic Laboratory (NPOL), a Kochi based laboratory of Defence Research and Development Organisation (DRDO).

    The four inducted sonar systems are:

    • ABHAY: It is an advanced Active-cum-Passive integrated SONAR system. It is designed and developed for the smaller platforms such as shallow water crafts and coastal surveillance/patrol vessels. It is capable of detecting, localizing, classifying and tracking sub-surface and surface targets in both its active and passive modes of operation.

    • HUMSA-UG: It is designed for upgrading the existing HUMSA SONAR system of the Indian Naval platforms. This system is proposed to be installed on seven ships of three different classes of ships.

    • NACS: It determines the in-situ performance of the SONAR systems, which are used to find the frequency-dependent 3-D transmission and reception characteristics of the SONAR. It is also used to measure the magnitude and phase characteristics of the SONAR transmission and reception electronics and the transducers.

    • AIDSS: The system stands for Near-field Acoustic Characterisation System. It is a distress SONAR. It is an Emergency Sound Signalling Device, which is used to indicate that a submarine is in distress and enable quick rescue and salvage.

    5. Which of following organisation has successfully carried out maiden flight of TAPAS 201 (RUSTOM – II), a Medium Altitude Long Endurance (MALE) Unmanned Aerial Vehicle (UAV) recently?
    a. DRDO
    b. ISRO
    c. BARC
    d. IIST

    Answer: a

    Explanation:

    The maiden flight of TAPAS 201 (RUSTOM – II), a Medium Altitude Long Endurance (MALE) Unmanned Aerial Vehicle (UAV) has successfully carried out by the Defence Research and Development Organization (DRDO) recently. The test flight took place from Aeronautical Test Range (ATR) at Chitradurga, a newly developed flight test range for the testing of UAVs and manned aircraft.

    Bangalore-based premier lab of DRDO, Aeronautical Development Establishment (ADE) has the credit of designing and developing this flight. It is the first R&D prototype UAV which got the certification and qualification for the first flight from the Centre for Military Airworthiness & Certification and Directorate General of Aeronautical Quality Assurance.

    6.  Recently which of the following guided missile destroyer commissioned into the Indian Navy?
    a. SONAR
    b. INS Chennai
    c. INS Vikramaditya
    d. INS Kolkata

    Answer: b

    Explanation:

    INS Chennai, guided missile destroyer has been commissioned into Indian Navy recently by Manohar Parrikar, India’s Defence Minister, at the Naval Dockyard, Mumbai. It was indigenously designed by the Indian Navy’s Directorate of Naval Design and constructed by Mazagon Dock Limited, Mumbai. The will be placed under the operational and administrative control of the Flag Officer Commanding-in-Chief, Western Naval Command.
