*            Passage - 1

For the first time laser light was created by scientists, using living biological material; a single human cell and some jellyfish protein. Seok-Hyun Yun, an optical physicist at Harvard Medical School and Massachusetts General Hospital in Boston created the living laser with his colleague Malte Gather. This was the first time that biological materials were used to build a laser and generate light from something living. Building a laser requires two things:

(i) A lasing material that amplifies light from an external source (a gain medium) and

(ii) An arrangement of mirrors (an optical cavity), which concentrates and aligns the light waves into a tight beam. Before the creation of living laser, the gain medium has only been made from non-biological substances, such as doped crystals, semiconductors or gases. But in living laser, the researchers used enhanced green fluorescent protein (GFP).

GFP makes jellyfish bioluminescent, which is used extensively in cell biology to label cells. Seok-Hyun Yun and his team engineered human embryonic kidney cells to produce GFP, then placed a single cell between two mirrors to make an optical cavity just 20 micrometres across. When they fed the cell pulses of blue light, it emitted a directional laser beam visible with the naked eye and the cell was not harmed. The width of the laser beam is tiny and fairly weak. It is brighter than natural jellyfish fluorescence, with a beautiful green colour.  

 

Read the passage carefully and tick the correct answers:  

 

  The chief importance in making the laser light was-

(a) It was made by using living biological material

(b) It was made of single human cell and jellyfish protein

(c) It was for the first time that biological materials were used

(d) It could generate light from something living

(e) None of these

 

 

  In making the living laser, the scientists used -

(a) Improved green fluorescent protein                               

(b) Non-biological substance

(c) Doped crystals, semiconductors and gases   

(d) Single human cell and jelly fish protein

(e) None of these  

 

 

  The passage provides information about________.

(a) Discovery of laser light with biological materials

(b) Invention of laser light with biological materials

(c) Laser light made from non-biological substances

(d) Use of enhanced green fluorescent protein for laser light

(e) None of these  

 

 

  The scientists found the width of the laser beam________.

(a) Tiny and weak

*            Passage - 2

Corruption is an epidemic that has dogged the Indian thinkers since Independence. Rajiv Gandhi's candid admission of the rot in the Indian governance and administration exemplifies the challenge that lies ahead of the nation. Accountability in public life is something that has evaded the imagination of the Indians; However, recent scandals in the Commonwealth Games, 2G spectrum allocation and even the Cash for Vote scam in the Parliament have forced the country to stand up against this menace that not only blemishes the face of the nation but also mars the development of the poor and the underprivileged. Several attempts by citizens and NGOs have led to enactment of laws like the Right to Information Act but it is also a fact that the scale of corruption and the scams has touched new heights. The alleged scam in the allocation of the 2G spectrum which led to the resignation and arrest of former Union Telecom Minister A. Raja is estimated to the tune of 1.76 lakh crore rupees as per a Report by the CAG. As India continues to rise to prominence in international affairs, it is of paramount significance that the civil society wakes up to the need of the hour and raise voice against corruption. Mere rise in the GDP will not give any direction to the country as dissatisfaction will brew if the divide between the rich and the poor continues to grow, thanks to corruption. Also, India has to improve governance and its polity if the country hopes to play the role of a leader in the 21st century.  

 

Read the passage carefully and tick the correct answers:  

 

  The country is reeling under severe doledrums due to_________.

(a) Economic instability

(b) Recent scandals

(c) Crisis in development of the poor and underprivileged

(d) 2G spectrum and Cash for Vote scam

(e) None of these  

 

 

  The passage urges the need of the hour ________.

(a) Improving of governance                     

(b) Divide between the rich and the poor

(c) Rise voice against corruption                

(d) Waking up of civil society

(d) International affairs

(e) None of these  

 

 

  In order to play a key role being the leader of the 21st century, India________.

(a) Should improve its governance and polity

(b) Dream of new heights

(c) Develop the poor and the underprivileged

(d) Evade the imagination of the Indians
