    The correct answer is (b) (ii) and (iii). Asthma and diabetes are non-communicable diseases. They do not spread through contact or infection. These are mostly caused by genetic, environmental or lifestyle factors. Typhoid and measles, on the other hand, are communicable diseases caused by pathogens and can spread from one person to another. Knowing the type of disease helps in prevention and treatment planning.

    (i) To stop the flu from spreading, the school should quickly identify and send sick students home. Regular cleaning of benches, doorknobs and washrooms is important. The school should encourage handwashing, provide sanitizers and ask students to wear masks. Morning announcements can raise awareness. Teachers should ensure physical distancing and monitor for symptoms. These steps together can reduce the risk of infection and protect everyone in school from falling ill.

     

    (ii) If my benchmate shows flu symptoms, I would kindly say, “You don’t seem well, maybe you should visit the nurse.” I wouldn’t blame or embarrass them but show care for their health. I’d keep some distance for safety while remaining friendly. This shows concern without being rude. Staying respectful helps maintain friendship while also protecting myself and others from getting sick. It’s important to act with both care and caution.

     

    (iii) To protect myself and others, I would wear a mask, wash my hands frequently and avoid touching my face. I’d avoid close contact with anyone sneezing or coughing and wouldn’t share food, bottles or stationery. I’d inform a teacher if someone looks very sick. Following hygiene rules, covering my nose when sneezing and staying home if I feel unwell are all important steps to stop flu from spreading at school.

    (i) Before travelling, visit a doctor for preventive medicines and pack mosquito repellents, nets and long-sleeved clothes. During the trip, stay indoors after dusk, apply repellent regularly and sleep under a mosquito net. Avoid areas with stagnant water. After returning, monitor for symptoms like fever, chills or weakness. If any appear, consult a doctor immediately. These steps help prevent malaria and ensure a safe trip for the whole family.

    (ii) I’d explain to my sibling that malaria spreads through mosquito bites and that mosquito nets and repellents act like shields. Nets protect us while we sleep and repellents keep mosquitoes away during the day. I’d say, “Just like we wear jackets to avoid cold, nets and creams protect us from bites.” By making it easy to understand and showing care, I’d help them take these precautions seriously and willingly.

    (iii) Ignoring health advisories in malaria-prone areas can lead to serious illness. Travellers may get infected through mosquito bites and suffer from high fever, chills and weakness. Some may require hospitalization. If they return home sick, the disease might spread to others. Missing out on preventive steps like using nets or medicines increases health risks. Health advisories are given to protect everyone’s well-being and should always be followed carefully.

  4. (i) I’d speak to my uncle gently, saying, “We care about you and want you to stay healthy. Smoking may seem cool, but it causes heart problems, cancer and even early death.” I’d remind him of his role in the family and how quitting can set a great example. I’d also suggest alternatives like yoga orRead more

    (i) I’d speak to my uncle gently, saying, “We care about you and want you to stay healthy. Smoking may seem cool, but it causes heart problems, cancer and even early death.” I’d remind him of his role in the family and how quitting can set a great example. I’d also suggest alternatives like yoga or hobbies and offer support. This approach shows love and concern without being harsh or disrespectful.

     

    (ii) If a friend offered me a cigarette, I would calmly say, “No thanks, I don’t want to harm my health.” I’d try to change the subject or walk away if needed. Peer pressure can be tough, but I’d remember my values and long-term health matter more. I might even share facts about smoking’s dangers. Saying no with confidence shows strength, not weakness and helps me stay true to myself.

     

    (iii) Schools can play a big role in preventing harmful habits like smoking. They can organize health workshops, awareness campaigns and sessions with doctors who explain smoking’s effects. Including anti-smoking messages in textbooks, showing real-life stories and encouraging students to speak up against peer pressure helps too. Creating clubs for sports, music or drama offers healthy alternatives. When students feel supported and informed, they’re more likely to say no to harmful substances.

    Vinita might say, “Saniya, do you know that antibiotics work only on bacteria, not viruses? So they can’t cure flu, cold or COVID-19.” She can also ask, “What happens if we take antibiotics for the wrong illness?” and “Have you heard of antibiotic resistance?” These questions can help Saniya think and realize that antibiotics are not a cure-all and must be used carefully to avoid harmful effects.
