Q25

Q25 Read the passage given below and answer the questions that follow with reference to the given passage.
In a timeframe of approximately half a century, nanotechnology has become the foundation for remarkable industrial applications and exponential growth. For example, in the pharmaceutical communities of practice, nanotechnology has had a profound impact on medical devices such as diagnostic biosensors, drug delivery systems, and imaging probes. In the food and cosmetics industries, use of nanomaterials has increased dramatically for improvements in production, packaging,shelf life, and bioavailability. Zinc oxide quantum dot nanoparticles show antimicrobial activity against food-borne bacteria, and nanoparticles are now used as food sensors for detecting food quality and safety. The most recent goals and accomplishments of each of the US federal entities listed on are summarized in the NSTC’s report titled, “Supplement to the President’s Budget for Fiscal Year 2015—The National Nanotechnology Initiative.” Today, nanotechnology impacts human life every day. The potential benefits are many and diverse. However, because of extensive human exposure to nanoparticles, there is a significant concern about the potential health and environmental risks. These concerns led to the emergence of additional scientific disciplines including nanotoxicology and nanomedicine. Nanotoxicology is the study of potential adverse health effects of nanoparticles. Nanomedicine, which includes sub sectors such as tissue engineering, biomaterials, biosensors, and bioimaging, was developed to study the benefits and risks of nanomaterials used in medicine and medical devices. Some of the potential benefits of medical nanomaterials include improved drug delivery, antibacterial coatings of medical devices, reduced inflammation, better surgical tissue healing, and detection of circulating cancer cells. However, due to lack of reliable toxicity data, the potential to affect human health continues to be a major concern.
In which fields does Nanotechnology not affect humans according to their usage?

A

Pharmaceutical uses

B

Health related Technologies

C

Day to day food consumption

D

Machinery Production

Q27

Q27 Read the passage carefully and answer the question:
Since these early beginnings India’s film industry has continued to flourish, growing in popularity, size and reach. There are many factors for this ongoing growth, one of them being the affordability of cinema in the country. From the early days onwards, India cinema venues have made films accessible to the wider public, providing cheap admission, with convenient extras being sold as buyable additions, not inbuilt in the price. With the vast economic gap that is found in India, this factor has allowed film to become an art form for the people, not just for the upper class. Interestingly, in the late 1920s the British government tried to promote UK film in India in an attempt to overtake the growing American cinema, and created the Indian Cinematograph Enquiry Committee. This programme failed with this aim however, with the committee favouring Indian produced films; it seemed that nothing could stop the growth of this national movement. With technology advancements, sound and dialogue became more and more implemented in Indian films throughout the 1930s, leading to a surge of song and dance in films, such as in Indrasabha and Devi Devyani. This element would take a stronghold in Hindi cinema, and is a renowned quality found in many Bollywood films being made today. Another influential factor in Bollywood’s growth was India’s independence in 1947. Proud in becoming an autonomous country, national cinema experienced a Golden Era from the 1940s to the 1960s. This era saw directors such as Satyajit Ray, Guru Dutt, Raj Kapoor and Vijay Bhatt create a wide range of classic films, further establishing and redefining Indian film. It was these influential filmmakers who paved the pathway for the future of Bollywood, and its present day position as one of the largest film industries in the world.
Which of the following could be inferred as the reason for the success of Indian Films?
A. Wider range of Classic movies
B. Embracing sounds and dialogues for entertainment
C. Being entitled as the autonomous country boosted the growth
D. Upsurge of musical audio and visual elements in the movies

A

Only B

B

A and C

C

All of these
