- Question 1 of 7
1. Question
1 pointsCategory: Science and TechnologyWhich among the following countries has launched world’s first fully electric cargo ship?
Correct
China launched world’s first fully electric cargo ship in Guangzhou, capital city of Guangdong province (November, 2017). It is the first ship in the world to use lithium ion battery. The ship will be mainly used to run in inland section of Pearl River for carrying coal for generation of electric power.

3. Question
1 pointsCategory: Science and TechnologyWith reference to chronic obstructive pulmonary disease (COPD), consider the following statements:
- COPD is one single disease that is caused due to cigarette smoking.
- COPD is preventable, but not curable.
Which of the statements given above is/are correct?
Correct
Statement 1 is incorrect. COPD is not one single disease but an umbrella term used to describe chronic lung diseases that cause limitations in lung airflow. It is not a simple smoker’s cough, but an under-diagnosed, life threatening lung disease. The most common symptoms of COPD are breathlessness, or a ‘need for air’, excessive sputum production, and a chronic cough. Daily activities, such as walking up a short flight of stairs, may become very difficult as the disease worsens.
According to WHO estimates, 64 million people have COPD and 3 million people died of COPD in 2004. Total deaths from COPD are projected to increase in the next 20 years, making it the third leading cause of death in the world unless urgent action is taken to reduce underlying risk factors, especially tobacco use and air pollution.
Statement 2 is correct. COPD is preventable, but not curable. Treatment can help slow disease progression, but COPD generally worsens slowly over time. Because of this, it is most frequently diagnosed in people aged 40 years or older. Chronic bronchitis and emphysema are terms that are no longer used and are now included within the COPD diagnosis.

6. Question
1 pointsCategory: Science and TechnologyWhich of the following professional (s) are more likely to run the risk of a permanent change in their cell’s DNA?
1. Researchers using Carbon-14 isotope
2. X-ray technician
3. coal miner
4. Dyer and painter
Select the correct answer using the codes given below:
Correct
X-rays can damage the cell and tissues and finally cause mutation, even excessive dose can lead to cancer. Researchers using C-14 isotopes and coal miners too expose to the radiations released in less concentrations continuously may lead to mutation in their cell’s DNA.
