Question 14 Marks
Your friend is planning to start a business. Study the following chart and suggest him/her in five to six sentences whether he/she should have franchisee of Tea or Coffee point.
Beverage preferences among the people in their middle ages.
Iced tea Cold-drinks Cold coffee Coffee Tea 
$06\%$$02\%$$12\%$$24\%$$56\%$
Answer
Based on the beverage preferences among people in their middle ages, your friend should consider having a franchise of Tea Point. The data shows that 56% of people prefer Tea, which is the highest among the options. In contrast, Coffee only accounts for 24%, and Cold Coffee is at 12%, both of which are lower than Tea. Additionally, Iced Tea (6%) and Cold Drinks (2%) also do not match the popularity of Tea. Given that Tea is the most preferred beverage in this age group, a Tea franchise would likely have more demand and business potential. Therefore, investing in a Tea Point franchise could be a more profitable decision.

My old school offered three mediums, but the new school has only one medium of instruction. There were 60 teachers in the old school, whereas the new one has 80, which helps in better individual attention. Both schools have playgrounds, science labs, uniforms, discipline, and a good atmosphere. The old school was close to my home, but the new school is far, so I have to travel more.

Study the following tabular information on conversion and write seven to eight sentences based on it:
Memory Size Conversion Table
Bytes
Kilobyte1,024Kilobytes
Megabyte1,048,5761,024Megabytes
Gigabyte1,073,741,8241,048,5761,024Gigabytes
Terabyte1,099,511,627,7761,073,741,8241,048,5761,024
Answer
Memory in computers is measured in bytes, and it increases step by step in powers of 1024. One kilobyte is equal to 1,024 bytes. One megabyte is equal to 1,048,576 bytes or 1,024 kilobytes. One gigabyte is equal to 1,073,741,824 bytes, which is also 1,048,576 kilobytes or 1,024 megabytes. As memory size increases, the values become very large. One terabyte equals 1,099,511,627,776 bytes, or 1,073,741,824 kilobytes, or 1,048,576 megabytes, or 1,024 gigabytes. These conversions are useful in understanding the size of data and storage devices like USB drives, hard disks, and cloud storage. Knowing memory conversions helps us choose the right storage for our needs.

In summer, people feel sweaty and uneasy, while during the rainy season, they may sometimes catch cold and fever. Nature looks bare and barren in summer, but during the rains, there is greenery everywhere. To protect ourselves in summer, we use fans and suncoats, while in the rainy season, we use raincoats and umbrellas. During summer, farmers are busy digging and cleaning the land, and in the rainy season, they sow seeds. Both seasons are important and bring different experiences to our lives.

13. Powerful rock music100 db
14. Motorcycle105 db
15. Thunder storm110 db
A sound above 130 decibels causes damage to hearing.
Answer
The loudness of sound is measured in decibels (db). Silence measures 0 db, while breathing is about 10 db. Soft sounds like wind in the trees or a whisper range from 20 to 30 db. Everyday sounds such as radio music, ticking clocks, or children playing fall between 30 to 80 db. Louder sounds like a vacuum cleaner or a lion's roar can reach 80 to 90 db. Extremely loud noises such as powerful rock music (100 db), motorcycles (105 db), or thunderstorms (110 db) can be harmful. Any sound above 130 db is dangerous and may cause hearing damage. Therefore, we must protect our ears from continuous exposure to high sound levels.

Question 104 Marks
Answer
As whalers reduced catches of the larger whales, they switched to smaller species. This is evident when we compare figures for the Antarctic catch of the larger sei whale with those for small minke whale. In 1985, fifteen times as many sei whales as minke whales were caught. By 1995, catches of both the species were virtually the same (9000). By the 2000, the situation had reversed and the number of minke whales killed more than doubled as compared to sei whales (6000). The graph shows that while the sei catch was reduced by 95% between 1985 and 2010, over the same period the minke whale catch was eight times greater. If these trends continue, the situation for the smaller species will be as bad as it used to be for the larger once.

The image displays various fielding positions of players in a cricket match against Australia, with both Indian and Australian cricketers depicted. M.S. Dhoni is positioned as the wicket-keeper, a crucial role behind the stumps. On the bowling end, Zaheer Khan is the bowler, preparing to deliver the ball. The diagram also illustrates an umpire, Billy Bowden, standing at the bowler's end. Ricky Ponting is shown at what appears to be a slip position, ready to catch edges. Michael Clarke is positioned at long-off, while Gautam Gambhir is at long-on, both deep in the outfield. Suresh Raina can be seen at short extra cover, a close-in fielding position. Yusuf Pathan is at square-leg, and Yuvraj is positioned at mid-wicket, both strategic spots for saving runs and taking catches. Ashish Nehra and Pragyan Ojha are also part of the fielding setup, with Ojha seemingly at fine-leg. The arrangement highlights a typical defensive field placement, with a mix of close-in catchers and outfielders to cover boundaries.

Question 194 Marks
Answer
The series of pictures illustrates a compelling story about two donkeys, initially tied to each other by a single rope, attempting to reach separate piles of grass. In the first few frames, both donkeys pull in opposite directions, each trying to reach their desired pile of grass. This individualistic effort leads to frustration and no success, as the rope prevents either donkey from reaching their goal. Recognizing their futility, they eventually stop pulling and look at each other, seemingly contemplating a new strategy. In a moment of realization, they then come together, demonstrating a shift from competition to cooperation. Finally, they both approach one pile of grass together, eating it collaboratively. Once that pile is finished, they move towards the second pile, again eating together. This sequence effectively conveys the message that cooperation and teamwork lead to success, whereas individualistic stubbornness can result in failure and unfulfilled desires.
