Direction: Read the following passage carefully:
It’s not cool to be fat, but that hasn’t stopped an obesity epidemic from occurring among young Americans. Childhood obesity increased from 5% in 1964 to about 13% in 1994. Today it’s about 20%, and rising. Children, on average, spend five to six hours a day involved in sedentary activities like watching TV, using the computer, and playing video games, which is partly to blame for this rising rate. Maybe it wouldn’t matter if they were active enough at other times, but most of them aren’t.
To make matters worse, children are bombarded with television advertisements for fast food chains and other providers of high-fat, high-sugar meals and snacks. These highly effective advertising campaigns, combined with a physically inactive lifestyle, have produced a generation of children who are at high risk for medical conditions associated with obesity.
The main health threat is the early development of type 2 diabetes (adult onset), particularly in children with a family history of the disease. Doctors report an increase in the number of young adolescents developing type 2 diabetes, which can lead to heart disease, high blood pressure, kidney disease, stroke, limb amputations, and blindness. People who develop diabetes in adolescence face a decreased quality of life and a shorter life expectancy, particularly if the disease progresses without treatment. It’s a scary prospect for our children, but in many cases, obesity and diabetes are preventable.
When kids spend most of their free time sitting in front of TVs and computers, they aren’t outside running, jumping, or participating in team sports that would keep their weight down. Parents should set limits on the time their children spend in passive activities. Pediatricians recommend restricting children to one or two hours a day in front of the TV and computer combined, although older children may need additional time for learning activities.
Parent involvement remains the most important key to healthy diets for our children. Programs to educate parents about nutrition are essential. Fast foods should be eaten only in moderation. Caregivers, who are often busy and in a hurry, must avoid the temptation to take their children to fast food restaurants or buy fast food for dinner at home. Changing eating habits and lifestyles is not easy, but the benefit to our children’s health is a wonderful reward for parents willing to take on the task.
Q. The most important factor to improve our children’s diet is _____.
  • a)
    parental involvement
  • b)
    not watching TV advertisements
  • c)
    not having fast foods
  • d)
    All of these
Correct answer is option 'A'. Can you explain this answer?

Direction: Read the following passage carefully:
Delhi tried very hard, but it was not enough. In the run up to D-Day, the sound of firecrackers had not been heard. The Supreme Court’s ban on its sale had made it difficult to acquire, but many people, including schoolchildren, had decided to break tradition for clean air. And until 7 pm on Diwali, most neighborhoods were quiet. Around that time the first sound of firecrackers exploding was heard, slowly building to a crescendo. But it was nowhere near the blitzkrieg of the past, not even half of it. And long before midnight, it was all over.
The bad news broke at dawn. It was a visibly smoggy morning. Air pollution levels peaked on Diwali night and remained dangerously high through Friday afternoon, as reflected in real-time monitoring data from the Central Pollution Control Board (CPCB) and the Delhi Pollution Control Committee (DPCC).
The CPCB, however, pointed to a silver lining. He said this year’s Air Quality Index (AQI) was better than Diwali’s in the past two years despite the harsh weather conditions. At Diwali last year (October 30, 2016), the city’s average AQI was in the “serious” category at 426, while the year before (November 11, 2015), it had been in the “very poor” category. ” at 327. This time, it was marginally lower at 326.
There are so many factors that affect air quality, from wind speed and direction to crop stubble burning in neighboring states, that it’s hard to definitively identify the main culprit. What must be recognized, however, is that at least most people are willing to stick with what may seem like unpleasant decisions for a better quality of life.
However, the data is troubling informed observers, particularly the massive spikes in levels of PM 2.5 (respirable fine particulate matter pollutants) and PM 10 (coarse particulate matter pollutants) on Thursday night after 10 p.m. p.m. Delhi peaked at 656 micrograms per cubic meter around midnight.
However, the data also shows that despite unfavorable weather conditions, the air quality at Diwali this year was better than last year. It hadn’t been as good in the two days before Diwali due to the intrusion of humid air from the southeast, coupled with prevailing calm wind conditions. The average mixing height (the height at which smoke or air rises, mixes and disperses) recorded on October 18 and 19 was 547 meters and 481 meters, respectively, according to the CPCB. It must be at least 1000 meters for a correct dispersion.
Q. The ‘bad news’ that broke at dawn was that
  • a)
    there was smog in the sky.
  • b)
    the air pollution levels were dangerously high.
  • c)
    CPCB released real time figures that were alarming.
  • d)
    All of the above.

Devansh Goyal answered


Explanation:

Bad News at Dawn:
- The bad news that broke at dawn was that the air pollution levels were dangerously high.
- This was evident from the visibly smoggy morning and the real-time monitoring data from CPCB and DPCC.

Reasons for Concern:
- The levels of PM 2.5 and PM 10 spiked significantly on Thursday night after 10 p.m., with Delhi peaking at 656 micrograms per cubic meter around midnight.
- Despite the slightly better Air Quality Index (AQI) compared to the past two years, the high levels of particulate matter pollutants raise serious concerns.

Factors Affecting Air Quality:
- Various factors such as wind speed, crop stubble burning in neighboring states, and weather conditions play a role in determining air quality.
- The intrusion of humid air from the southeast and calm wind conditions in the days leading up to Diwali contributed to the poor air quality.

Silver Lining:
- The CPCB noted that this year's AQI was marginally lower compared to the previous years, despite the harsh weather conditions.
- This indicates that efforts to reduce firecracker usage and promote cleaner air may be having some positive impact.

In conclusion, while there are concerns about the high pollution levels on Diwali night, there is a slight improvement in air quality compared to previous years. However, continued efforts and awareness are needed to address the underlying factors contributing to air pollution in Delhi.

Q. Early development of type 2 diabetes is normally found in children with
  • a)
    sedentary lifestyles
  • b)
    strict parents
  • c)
    voracious appetites
  • d)
    a family history of the disease
Correct answer is option 'D'. Can you explain this answer?

Upasana Roy answered
Family History of the Disease
Children who develop early onset type 2 diabetes usually have a family history of the disease. This means that genetics play a significant role in predisposing these children to diabetes.

Genetic Predisposition
Genetic factors can make some individuals more susceptible to developing type 2 diabetes at a younger age. If a child has a parent or sibling with type 2 diabetes, they are at a higher risk of developing the condition themselves.

Increased Risk
Having a family history of type 2 diabetes increases a child's risk of developing the disease earlier in life. It is important for parents to be aware of their family's medical history and take proactive steps to prevent or manage diabetes in their children.

Preventive Measures
While genetic predisposition is a risk factor for early onset type 2 diabetes, it is not a guarantee that a child will develop the disease. By promoting a healthy lifestyle, including regular physical activity and a balanced diet, parents can help reduce the risk of diabetes in their children.

Conclusion
In conclusion, a family history of type 2 diabetes is a significant factor in the early development of the disease in children. By understanding the role of genetics and taking preventive measures, parents can help protect their children from the potential health risks associated with diabetes.

Serious Tone:
- A factual passage is meant to provide accurate information, so the tone should be serious to convey the importance and gravity of the subject matter.
- The author avoids using humor or lighthearted language that could undermine the seriousness of the topic.

Objective Tone:
- Objectivity is a key aspect of a factual passage. It means that the author presents information without personal bias or emotional influence.
- The author relies on evidence, facts, and logical reasoning to support their claims, rather than trying to persuade the reader to agree with a particular viewpoint.
- By maintaining an objective tone, the author allows the reader to form their own opinions based on the presented information.

Why not the other options?
- Emotional and persuasive: Factual passages are not meant to evoke strong emotions or convince the reader to take a specific stance. Instead, they focus on presenting information accurately and objectively.
- Humorous and lighthearted: Factual passages typically deal with serious or important topics, and using humor or lighthearted language could undermine the gravity of the subject matter.
- Sarcastic and critical: Factual passages aim to inform and educate, not to criticize or mock. Using sarcasm or a critical tone would detract from the objective nature of the passage.

In conclusion, the tone of a factual passage is serious and objective. This allows the author to present information without personal bias, enabling the reader to make their own informed judgments based on the presented facts.

Devansh Goyal answered

Factors affecting air pollution on Diwali:

- School children bursting crackers: While school children bursting crackers can contribute to air pollution on Diwali, it is not the sole factor responsible for it. There are various other sources of pollution during the festival.

- Wind conditions: Strong winds can help in dispersing pollutants and reducing air pollution levels. However, if the wind direction is unfavorable, it can lead to the accumulation of pollutants in the air.

- Motor vehicles: The emissions from motor vehicles can also contribute significantly to air pollution on Diwali. Reduced vehicular movement can help in lowering pollution levels.

- Overall impact: It is important to note that a combination of factors, including firecrackers, wind conditions, and vehicular emissions, contribute to air pollution on Diwali. Hence, eliminating just one factor may not completely eliminate air pollution during the festival.

Doctors report an increase in the number of young adolescents developing type 2 diabetes, which can lead to heart disease, high blood pressure, kidney disease, stroke, limb amputations, and blindness. People who develop diabetes in adolescence face a decreased quality of life and a shorter life expectancy, particularly if the disease progresses without treatment. It’s a scary prospect for our children, but in many cases, obesity and diabetes are preventable.
When kids spend most of their free time sitting in front of TVs and computers, they aren’t outside running, jumping, or participating in team sports that would keep their weight down. Parents should set limits on the time their children spend in passive activities. Pediatricians recommend restricting children to one or two hours a day in front of the TV and computer combined, although older children may need additional time for learning activities.
Parent involvement remains the most important key to healthy diets for our children. Programs to educate parents about nutrition are essential. Fast foods should be eaten only in moderation. Caregivers, who are often busy and in a hurry, must avoid the temptation to take their children to fast food restaurants or buy fast food for dinner at home. Changing eating habits and lifestyles is not easy, but the benefit to our children’s health is a wonderful reward for parents willing to take on the task.
