6)   Bedaquiline drug is being tested to fight

a. Malaria
b. Zika
c. Yellow fever
d. TB
Answer  Explanation  Related Ques



  • A pilot programme to test the toxicity, particularly cardio-toxicity, of bedaquiline drug (for combating multidrug- resistant TB) in the Indian population, to assess its ability to achieve culture conversion and to check the feasibility of using the drug to treat MDR-TB patients will start in India.
  • Only those resistant to both rifampicin and isoniazid, the first-line TB drugs, will be enrolled.
  • As per the WHO’s recommendation, bedaquiline will be given to patients, besides the regular multidrug treatment regimen. Unlike clinical trials, the six institutions will not enroll a certain number of patients each. Instead, patients willing to participate in the programme will be enrolled on a first come, first served basis.

7)   Recently a new technology has been developed for communication called as Li-Fi. Li-Fi is

a. Light Fit
b. Lithium Fiber
c. Light Fiber
d. Light Fidelity
Answer  Explanation  Related Ques

ANSWER: Light Fidelity


  • Prof. Harald Haas of the University of Edinburgh coined the term Li-Fi in 2011.
  • Light waves instead of radio frequency waves will be used to carry data. The data from internet flows into a device which is connected to a LED bulb. Then the light containing data from this bulb falls on a receiver or a dongle connected to the computer.
  • RF (radio frequency) spectrum would not be enough considering the rate of growth of wireless data communication. The visible light spectrum was much larger.
  • The use of the light spectrum for Li-Fi overcomes the issues in traditional wireless communication, like the shortage of spectrum and network disruption because of interference.
  • In Li-Fi, anyone who has access to light can access the Internet. The system also allows users to move from one light source to another without losing their network connection.
  • For connecting to the Internet in the night the stream of photons can be reduced to a minimal level that won’t produce visible light but enough to carry data.
  • Though Li-Fi was poised to compete with Wi-Fi, it was not meant to replace it.
  • The Li-Flame is described as the world’s first true Li-Fi system. Latest product is LiFi-X. First product is Li-1st, second Li-Flame.

8)   Which of the following is/are true regarding Li-Fi technology?

1) It does not work under water unlike current radio frequency communication.
2) It cannot pass through walls.

a. Only 1
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
Answer  Explanation  Related Ques

ANSWER: Only 2


  • Li-Fi works under water as well.
  • Though the inability of light rays to pass through walls and similar structures is seen as a major drawback of this technology, it is an advantage since restriction by walls provides more security to the network and eliminates the risk of the signal leakage to eavesdropping.
  • Visible light spectrum is available in plenty, unlimited, unlicensed and free to use.
  • Bulb gives light as well as internet access.
  • Normal LED bulb can be used and no special bulbs needed.
  • Low interference leads to very high data speed.
  • Not harmful, unlike RF that can interfere with electronic circuitry.
  • It can achieve about 1000 times data density of Wi-Fi, as light can be contained in an area.
