Directions: Read the following passage carefully and choose the best answer to each question out of the four alternatives.

The most logical and intelligent people seem to go berserk when talking about snakes. Recently a reputed scientist said with a wise look in his eyes that sand boas have two heads. The other day someone walked into my office and stated that in his village at least cobras mate with rat snakes. About other places he was not sure, he added modestly, but that was how it was in his village.

These stories about snakes are myths. Sand boas have only one head; vine snakes do not peck your eyes out; no snake will drink milk. But it is interesting to try and trace the origin of these untruths. The one about the sand boas two heads obviously exists because the short, stumpy tail of this snake looks remarkably like the head, an effective device to fool predators. Or take the one about vine snakes pecking at eyes. It was ‘probably started by a vine snake that had a bad aim, as snakes, when provoked, will bite the most prominent projection of the offender, which is usually the nose.

But the most interesting one is about snakes coming to the scene of killing to take revenge. It so happens that when injured or under stress, a snake exudes, a large quantity of musk. Musk is a powerful sex attractant, the snakes’ equivalent of after-shave lotion. So after a snake is killed, the ground around still has this smell and naturally a snake of the same species passing by will lick its lips and come to investigate. The killer of the snake, who is probably worried if the pooja he performed was adequate to liquidate the killing of a snake, sees the second snake and is convinced that it was not.

The Irula tribals have a good answer to the query about whether cobras have jewels in their heads; “If they did, we wouldn’t be snake catchers, we would be rajas!”

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

The Indian Space Research Organisation (ISRO) announced another successful mission. ISRO chairman S. Somanath said that three small satellites successfully separated and were injected into orbit.

ISRO had launched three small satellites powered by its SSLV-D2 launch vehicle from Satish Dhawan Space Centre at Sriharikota on February 10, 2023 at 09:18 AM IST. The launch vehicle was carrying EOS-07, Janus-1 & AzaadiSAT-2 satellites and aimed to inject them into a 450 km circular orbit. The launch took place at the first launch pad at SDSC SHAR, Sriharikota.

The SSLV-D2 had to take a 15 minutes flight to inject EOS-07, Janus-1 and AzaadiSAT-2 satellites into 450 km circular lower orbit. “It is configured with three solid propulsion stages and a velocity terminal module. It is a 34 m tall, 2 m diameter vehicle having a lift-off mass of 120 t,” said ISRO. The EOS-07 satellite weighs 156.3 kg and is made by ISRO. About 13 minutes into its flight, the SSLV rocket ejected EOS-07 and soon after that the other two satellites Janus-1 and AzaadiSAT-2 were ejected — all at an altitude of 450 km, said ISRO.

With the new rocket in its portfolio, ISRO will have three rockets — Polar Satellite Launch Vehicle (PSLV) and its variants (cost about Rs 200 crore), Geosynchronous Satellite Launch Vehicle (GSLV-MkII cost about Rs 272 crore and LVM3 Rs 434 crore) and SSLV (Development cost of three rockets about Rs 56 crore each) and production cost may go down later.

“New experiments include mm-Wave Humidity Sounder and Spectrum Monitoring Payload. Janus-1, a 10.2 kg satellite belongs to ANTARIS, USA. A 8.7 kg satellite AzaadiSAT-2 is a combined effort of about 750 girl students across India guided by Space Kidz India, Chennai,” it added.

SSLV caters to the launch of up to 500 kg satellites to Low Earth Orbits on ‘launch-ondemand’ basis. “It provides low-cost access to Space, offers low turn-around time and flexibility in accommodating multiple satellites, and demands minimal launch infrastructure,” as per a statement by ISRO
