Question : Read the passage and answer the following questions.
IIT Delhi researchers have designed and fabricated a device that can generate electricity from water drops, raindrops, water streams, and even from ocean waves using "Triboelectric Effect" and "Electrostatic Induction". The device is called "Liquid-solid Interface Triboelectric Nanogenerator". The generated electricity can be stored in batteries for further use. Triboelectric effect is a known phenomenon for a long time, and in this effect, charges are generated when two surfaces are in friction. The best example we see are sparkling lights when we move the blankets/jackets.

The device has a very simple structure consisting of specially designed nanocomposite polymers and contact electrodes and can generate a few Milliwatt mW power, which is sufficient to power small electronic devices like watches, digital thermometers, radio frequency transmitters, healthcare sensors, pedometers. When compared to conventional methods, such as the use of the piezoelectric effect, the present device can generate significantly more electricity.

The researchers successfully incorporated nanostructures into a polymer matrix, which enhanced the film's surface roughness, polarizability, and hydrophobicity, among other characteristics, as a result. Due to the enhancement in the above property, the flexible film is used to fabricate the device where raindrops have just to slide down and can generate electricity. The artificially created rough surface allows to generate more charge and superhydrophobic properties of the solid surface help to roll the water drop without getting stick to the surface.

The IIT Delhi research team also explored the underlying mechanism of the electricity generated when the water drop comes in contact with the solid surface and it is shown that saline water drops generate more electricity. The researchers also showed that the device can even work with ocean waves, where the water is saline, and through the ocean waves contacting the surface of nanocomposite polymer film, electricity is generated.

Solution : The correct answer is (a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.

The assertion states that the private sector's involvement in healthcare can improve service quality and increase accessibility, which is correct. The private sector, including private healthcare providers, pharmaceutical companies, and medical technology firms, can contribute to improving the healthcare sector in various ways. Private healthcare providers often bring in investments that can be used to enhance infrastructure, acquire advanced medical technologies, and expand healthcare facilities. They also tend to introduce innovative practices and business models that can lead to improved service quality, efficiency, and patient experience. Additionally, private sector participation can create competition in the healthcare market, which can incentivize improvements in service delivery and overall healthcare system performance.

The reason provided states that private healthcare providers can bring in investments and innovative practices, and this is the correct explanation of the assertion. Private sector involvement in healthcare can bring financial resources through investments, which can be used to modernize healthcare infrastructure, upgrade medical equipment, and attract skilled healthcare professionals. Private providers are often driven by profit incentives, which can encourage them to introduce innovative practices to attract more patients, streamline processes, and deliver high-quality care. These innovative practices can lead to advancements in medical technology, new treatment approaches, and improved healthcare delivery models.

Therefore, both the assertion and reason are correct, and the reason serves as the correct explanation for why the private sector's involvement in healthcare can improve service quality and increase accessibility.

Question : Assertion: Pakistan has a higher infant mortality rate compared to India and China.

Reason: Greater access to healthcare facilities and awareness about proper healthcare practices contribute to high infant mortality in Pakistan.

Option 1: Both assertion and reason are true, and the reason is the correct explanation of the assertion.

Option 2: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

Option 3: Assertion is true, but the reason is false.

Option 4: Assertion is false, but the reason is true.

Team Careers360 24th Jan, 2024

Correct Answer: Assertion is true, but the reason is false.


Solution : The correct option is:
c) Assertion is true, but the reason is false.

The assertion is true. Pakistan does indeed have a higher infant mortality rate, which is the number of deaths of infants under one year of age per 1,000 live births, compared to India and China.

However, the reason provided is false. Greater access to healthcare facilities and awareness about proper healthcare practices are more likely to contribute to lower infant mortality rates rather than higher rates. Countries with better access to healthcare services and increased awareness about proper healthcare practices tend to have lower infant mortality rates. Therefore, the reason does not provide a correct explanation for the higher infant mortality rate in Pakistan.

Therefore, the assertion is true, but the reason is false.

Question : The term "e-waste" refers to:

Option 1: Waste generated by electronic devices

Option 2: Waste generated by industrial processes

Option 3: Waste generated by healthcare facilities

Option 4: Waste generated by construction activities

Team Careers360 24th Jan, 2024

Correct Answer: Waste generated by electronic devices


Solution : The correct answer is (A) Waste generated by electronic devices.

The term "e-waste" refers to electronic waste, which includes discarded or obsolete electronic devices. These devices can include computers, laptops, smartphones, tablets, televisions, printers, refrigerators, and other electrical or electronic equipment. E-waste may also include components and parts of these devices.

E-waste is a growing concern due to the rapid advancement of technology, leading to shorter product lifecycles and increased electronic consumption. Improper disposal of e-waste can have harmful environmental and health impacts. Many electronic devices contain hazardous materials such as lead, mercury, cadmium, and flame retardants, which can contaminate soil, water, and air if not managed properly.

Proper management of e-waste involves recycling and responsible disposal to recover valuable materials and prevent environmental pollution. Recycling e-waste allows for the recovery of valuable metals and other components, reducing the need for raw material extraction and minimizing the environmental impact of electronic devices.
