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

Read the given passage and answer the questions that follow.

Santiniketan embodies Rabindranath Tagore’s vision of a place of learning that is unfettered by religious and regional barriers. Established in 1863 with the aim of helping education go beyond the confines of the classroom, Santiniketan grew into the Visva Bharati University in 1921, attracting some of the most creative minds in the country.

He developed a curriculum that was a unique blend of art, human values and cultural interchange. Even today, in every step, in every brick and in every tree at Santiniketan, one can still feel his presence, his passion, his dedication and his pride in the institution. In 1862, Maharishi Debendranath Tagore, father of Rabindranath, was taking a boat ride through Birbhum, the westernmost corner of Bengal, when he came across a landscape that struck him as the perfect place for meditation. He bought the large tract of land and built a small house and planted some saplings around it. Debendranath Tagore decided to call the place Santiniketan, or the ‘abode of peace’, because of the serenity it brought to his soul. In 1863, he turned it into a spiritual centre where people from all religions, castes and creeds came and participated in meditation.

In the years that followed, Debendranath’s son Rabindranath went on to become one of the most formidable literary forces India has ever produced. He wrote in all literary genres but he was first and foremost a poet. As one of the earliest educators to think in terms of the global village, he envisioned an education that was deeply rooted in one’s immediate surroundings but connected to the cultures of the wider world.

Located in the heart of nature, the school aimed to combine education with a sense of obligation towards the larger civic community. Blending the best of western and traditional eastern systems of education, the curriculum revolved organically around nature with classes being held in the open air. Tagore wanted his students to feel free despite being in the formal learning environment of a school, because he himself had dropped out of school when he found himself unable to think and felt claustrophobic within the four walls of a classroom. Nature walks and excursions were a part of the curriculum, special attention was paid to natural phenomena and students were encouraged to follow the life cycles of insects, birds and plants.

The rural paradise of Santiniketan, Tagore’s erstwhile home, has become a thriving centre of art, education and internationalism over the years.

Rabindranath was a ‘formidable’ literary force. This implies he was:

Direction: Read the given passage carefully and answer the questions that follow. Certain words are printed in bold to help you locate them while answering some of these.

If you’re concerned that automation and artificial intelligence are going to disrupt the economy over the next decade, join the club. But while policymakers and academics agree there’ll be significant disruption, they differ about its impact.

On one hand, techno-pessimists argue that new forms of automation will displace most jobs without creating new ones. In other words, most of us will lose our jobs. On the flip side of the debate, techno-optimists contend that continued investments in education and research and development will offset the job losses and generate many new human tasks that complement AI.

Researchers have been studying jobs that involve digital skills for years to try to understand their merit. But what does it really mean for a job or skill to be “digital”?

In earlier research, all it meant was that a worker used a computer. Since nearly all workers use a PC today, we need a more refined definition of digital skills that takes into account how much a job depends on doing things like programming, crunching data in Excel spreadsheets and even using a smartphone.

In a particular research, a new way was created to measure digital or information technology skills in the labour market based on how frequently they’re used in an occupation. For example, how much time does a financial adviser spend analyzing data or an event planner use a computer?

It was found that workers in occupations that rank higher in IT industry earn more than demographically similar peers in other occupations – and that this earnings gap has been growing. Not only that, but it was also found something interesting on the impact of a college degree on the lifetime earnings of a person in IT industry. Historically, workers with a college degree have earned a lot more than peers without one. Even the level of the college makes a difference. Recent research has shown that this so-called college premium has been flattening. The main cause, according to the analysis, is that the college premium for occupations requiring fewer digital skills has been declining, while it has been rising for those we identified as digital jobs such as software developers, programmers and aerospace engineering. At least some of the flattening in the college premium is due to the increasing number of bachelor’s degrees that convey few skills that are valued in the marketplace.

Another research compares the measures of job quality – such as a sense of purpose, enjoyability and career advancement – with income, occupations and a range of demographic characteristics. It found that jobs that require greater interaction with technology tended to score higher in quality, particularly in terms of measures like career advancement.

The fact that these jobs not only pay more but also provide greater levels of employee satisfaction and engagement paints a more optimistic picture about the future of work. And that gives hope, particularly since the digital economy is growing at a pace nearly four times faster than the broader economy.

The key is making tomorrow’s jobs “robot-proof” by designing them in a way that takes advantage of the digital skills described above. And universities must play a big role in this by identifying what a good job looks like and ensuring future generations learn the necessary skills.

A “digital” job or skill means __________.
 A. The remuneration & perks generated by utilizing the digital or information technology skills
 B. A worker using a computer
 C. Frequency of using digital or information technology skills
