Read the following passage and answer the questions given after it.
Comprehension:

At a number of places in the Kashmir Valley, security forces have put coils of razor wire on roads to enforce restrictions on movement. Concertina wire or razor wire fences are used along territorial borders and in areas of conflict around the world, to keep out combatants,
terrorists, or refugees.

The expandable spools of barbed or razor wire get their name from concertina, a hand-held musical instrument similar to the accordion, with bellows that expand and contract. Concertina wire coils were an improvisation on the barbed wire obstacles used during World War I. The flat, collapsible coils with intermittent barbs or blades were designed to be carried along by infantry, and deployed on battlefields to prevent or slow down enemy movement.

The Englishman Richard Newton is credited with creating the first barbed wire around 1845; the first patent for “a double wire clipped with diamond shaped barbs” was given to Louis François Janin of France. In the United States, the first patent was registered by Lucien B Smith on June 25, 1867, for a prairie fence made of fireproof iron wire. Michael Kelly twisted razor wires together to form a cable of wires. The American businessman Joseph F Glidden is considered to be the father of the modern barbed wire. He designed the wire with two intertwined strands held by sharp prongs at regular intervals.

Barbed wire was initially an agrarian fencing invention intended to confine cattle and sheep, which unlike lumber, was largely resistant to fire and bad weather. An advertorial published in the US in 1885 under the title ‘Why Barb Fencing Is Better Than Any Other’, argued that “it does not decay; boys cannot crawl through or over it; nor dogs; nor cats; nor any other animal; it watches with Argus eyes the inside and outside, up, down and lengthwise; it prevents the ‘ins’ from being ‘outs’, and the ‘outs’ from being ‘ins’, watches at day-break, at noontide, at
sunset and all night long…” Barbed wire was put to military use in the Siege of Santiago in 1898 during the Spanish- American War, and by the British in the Second Boer War of 1899-1902 to confine the families of the Afrikaans-speaking Boer fighters.

World War I saw extensive use of barbed wire — and German military engineers are credited with improvising the earliest concertina coils on the battlefield. They spun the barbed wire into circles and simply spread it on the battlefield. Without using any support infrastructure like poles etc. this was more effective against the infantry charge by Allied soldiers.

The fence erected by India along the Line of Control to keep out terrorist infiltrators consists of rows of concertina wire coils held by iron angles. They are now commonly seen and are used to secure private properties as well.

Read the following passage and answer the questions given after it.
Comprehension:

LAST WEEK, scientists from all corners of India descended on Ahmedabad to remember the architect of India’s space programme, a man whom the late president, APJ Abdul Kalam, had famously termed “Mahatma Gandhi of Indian Science”.

They were there to launch celebrations on the birth centenary of Vikram Sarabhai, 47 years after his death at the age of 52, by when he had founded 38 institutions that are now leaders in space research, physics, management and performing arts.

Former director of the Space Applications Centre Pramod Kale was a 19-year old science graduate from MS University of Baroda, besotted by space technology, when he first met Sarabhai. “In May 1960, I went to Ahmedabad to meet Dr. Sarabhai. “I met him and ended up talking for two hours,” Kale says.

By June that year, Kale had done exactly as Sarabhai had advised him and taken up a master’s course at Gujarat University. In 1962, when Sarabhai was looking at studying the magnetic equator, Kale went on to be among the first few to go to NASA to learn radar tracking. The room resounded with many such memories. Former ISRO chairman K Kasturirangan remembered how they ran into some trouble at the Physical Research Laboratory (PRL), founded in 1947 by Sarabhai, in their attempts to fly a balloon at 4 am, when in sailed Sarabhai. “He told us had the flight been successful, you would not have learnt even half of what you learnt because of that initial problem,” said Kasturirangan.
Many of those who had collected in Ahmedabad in Sarabhai’s memory were teenagers when they first met him. Gandhinagar-based entrepreneur K Subramanian was 19 and a student of National Institute of Technology, Tiruchirappalli, working on a summer project at PRL, when a man in a kurta-pyjama walked in and began turning all the wastepaper bins upside down, inspecting their contents and putting them back again. “I asked a colleague who that was and was told it is Dr Vikram Sarabhai. He had come to check how much waste the lab was generating,” laughs Subramanian.

Born to Ambalal and Sarla Devi, Ahmedabad’s leading textile-mill owners, Vikram Sarabhai showed creative promise early. He was 15 when he built a working model of a train engine with the help of two engineers, which is now housed at the Community Science Centre (CSC) in Ahmedabad. The CSC was Vikram’s way of providing other children the privileges he had, of experimental research, says his son Kartikeya, 71, adding how his father wished to work with children at the science centre after he retired.

“He was essentially a researcher, and believed that people, especially children, should be allowed to think freely and come up with solutions on their own,” recalls Kartikeya, who founded the Centre for Environment Education in 1984. Kartikeya is carefully piecing together all the dog-eared notes he is discovering in the recesses of their three grand homes — Shanti Sadan, The Retreat and Chidambaram.
To inspire the young to dream like Sarabhai, Kartikeya is building a permanent exhibition gallery on the Sabarmati Riverfront, expected to open this November.
