Communication is an important part of human development. Our curriculum also emphasis a great important on communication skills, and mostly in Indian curriculum, students learn atleast 3 languages up till their middle school. Of all the languages, English language is most popular, with its regional and global acceptability. There are many aspect of English language, including literature, grammar, writing . In this article, we have covered reading comprehension part of English language with exercises from CBSE class 7 English on unseen passages. Student from ICSE and state boards or students preparing for IELTS, TOEFL can also practice these reading comprehension exercises and prepare for their English exams.

A rainy day is a sensory experience, blending nostalgia and simple joys, especially those from childhood. I vividly recall our family’s early days in a newly developed colony near my father’s workplace. The roads were unpaved, and after every heavy downpour, they turned into rivers of muddy water. Our school bus couldn’t reach our house, forcing us to wade through knee-deep water for nearly 300 meters. Our parents ensured that we were well prepared. Textbooks and notebooks were wrapped in plastic sheets to keep them dry, and our schoolbags also had spare socks and shoes, all sealed to survive the rain. My ever-cautious mother would even insist on a spare set of clothes. In those days, the ideas of reducing plastic use or having lighter schoolbags hadn’t gained traction, so we were well equipped for the daily watery adventure.
Each morning, armed with umbrellas, and our trousers rolled up, we embarked on the monsoon trek. It was a challenge, as scooters and bikes splashed us while we carefully avoided potholes and stones hidden beneath the water. Once we reached school, we would be greeted by rows of wet shoes and umbrellas. The air smelled of rain-soaked leather, and our waterproofed belongings were eagerly unwrapped, with the hope that they had withstood the downpour
- Question 1- What makes rainy day a sensory experience?
- Question 2 – How did author prepare for the rainy days during school times
- Question 3 – What did author described about the monsoon trek

“Jet systems like Porphyrion appear to be among the most energetic spectacles that have occurred in the universe since the Big Bang,” said Caltech astrophysicist Martijn Oei, lead author of the study published in the journal Nature, opens new tab, referring to the event that initiated the universe about 13.8 billion years ago.
“The general understanding is that jets are formed when magnetized material falls onto a rotating black hole,” added astrophysicist and study co-author Martin Hardcastle of the University of Hertfordshire in England. “They need to be sustained by a continued infall of matter into the black hole, something of the order of one solar mass (the mass of the sun) a year of material.”
Such jets, not visible to the naked eye, start out small and grow over time.
“We’ve known for a while that black holes can generate these jets. But what is interesting is that to generate a large structure like this, the jets must stay on for a long time – about a billion years,” Hardcastle said.
The Porphyrion jets reach far beyond their home galaxy, with an energetic output equivalent to trillions of stars like the sun.
“That is equivalent to the energy released during the most cataclysmic cosmic collisions: for example, those that occur when two galaxy clusters, each sometimes containing thousands of galaxies, merge together,” Oei said.
“The fact that it extends so far from its parent black hole means that it may be carrying energy, particles and magnetic fields into the voids in the cosmic web, the gaps between groups and filaments of galaxies which we know make up the large-scale structure of the universe. This may help us to understand the ubiquitous magnetic fields in the present-day universe,” Hardcastle said.
Such jets could heat up gas in interstellar space, shutting down the formation of new stars that requires cold clouds of gas, and could damage habitable planets, the researchers said.
The Milky Way’s supermassive black hole, in its current quiescent state, does not have such jets.
“The key finding is that jets from black holes can, if circumstances are right, become as large as the universe’s major cosmic structures – galaxy clusters, cosmic filaments, cosmic voids,” Oei said. “This means that individual black holes can have a sphere of influence that extends way beyond the galaxy in which they reside.”
- Question 1- What is Porphyrion? Explain key finding on Porphyrion.
- Question 2- How are jets formed and sustained in universe?
- Question 3- What are the dangers from jets in universe ?

China has emerged as the world’s top producer of generative AI patents, but it is struggling to turn many of its ideas into action thanks to US export controls and longstanding struggles with its innovation culture at home.
In July, the UN’s intellectual property agency reported that China had filed more than 38,000 generative AI patents over the past decade, more than all other countries combined.
Chinese companies and institutions rank in the global top 10 patent holders, including Tencent, Ping An Insurance, Baidu, and the Chinese Academy of Sciences, according to data from the World Intellectual Property Organization (WIPO).
Four US companies are in the top 10, but Silicon Valley and US research institutions filed just 6,276 over the same period from 2014-2023. South Korea, in third place, filed 4,155 inventions, followed by 3,409 from Japan, and 1,350 from India, according to WIPO data.
Despite this flurry of activity, however, China is still behind the US in terms of impact because the high number of patents only tells part of the story, according to Van Anh Le, an assistant professor in intellectual property law at Durham University in the United Kingdom.
“The sheer number of patents filed or granted is often mistakenly seen as a direct indicator of innovation. A high volume of patents can be driven by factors unrelated to groundbreaking innovation, such as strategic filings, differing national policies, or even non-innovative motives,” Le said. Patents are also designed to protect innovation but do not necessarily guarantee their commercial success, she added.
- Question 1- Which countries are leading generative AI patents?
- Question 2- Which are top companies and institutions in Generative AI in China?
- Question 3- What are key challenges with Generative AI patents in China?
- Question 4- Summarize the passage in 50 words
