The statement is true. Organisms that can withstand adverse conditions, beautiful flowers, amazing animals, effective vaccines, food crops, etc. can be developed through biotechnology.

The pentose sugar in DNA is deoxyribose and in RNA it is ribose. The difference between the sugars is the presence of the hydroxyl group on the second carbon of the ribose and hydrogen on the second carbon of the deoxyribose.

One cannot count on fingers the negative aspects the modern lifestyle has to offer. There is stress, pressure, fear, insecurity and worry. In order to relieve yourself of all these miseries, one can indulge in creative activities from time to time. Making time for yourself and what you love without worrying about a productive outcome is a crucial thing many people tend to ignore in the hustle and bustle of daily lives. Secondly, one can read a good book or even meditate. Long walks in the lap of nature are not to be underestimated because nature has its own healing power. Apart from these, a short weekend getaway, movie night with friends or even alone at home can be done in order to dissociate oneself from the routine.

Yes, there are a lot of instances that tell us about the intersection of time and space in the story. First intersection being the one between the first two levels of the Grand Central Station and its third level which is based somewhere in the 1890s whereas the former exists in the present times. Also when Charley went to buy tickets for Galesburg which existed in 1894 while he and his wife exists in the present times. Not to ignore the old fashioned architecture of the third level in contradiction to the modern interiors of the first two levels. Lastly, the letter dated 18th July, 1982 that Charley found also throws light upon the intersection of time and space as both the sender (Sam) and the receiver (Charley) exist in the present times.

Philately:

• The word "philately" is the English transliteration of the French "philatélie", coined by Georges Herpin in 1864.
• Philately is the study of postage stamps and postal history.
• It also refers to the collection, appreciation and research activities on stamps and other philatelic products.
• National Philately Day is celebrated on 13 October throughout the country.

Thus, philately is related to the collection of stamps.

While a lot of the world’s greatest inventions were made by people who were criticised for their ideas. Audiences used to mock at them for being illogical. Sighting the example of Thomas Edison who invented the light bulb, no one believed in him at first but all he had was an idea and its realistic projection in mind. The idea here tells us how important it is to sometimes follow one’s insight and have hope for it holds the capacity to change the world through its futuristic projections.

Philately does indeed help in keeping the treasures of past alive. It gives one a chance to revisit and embrace the past of one’s existence. Some of the other ways in which it can be done is by keeping a record of all the letters, ancient manuscripts, things that are discontinued but were a significant part of the past, images, videos and written records of experiences. Human beings are a collection of all the experiences they have been through. Their tendency to connect with the past from time to time helps them stay connected to the roots while helping them to face the present and future challenges with more strength. Connecting with the future on the other hand, is just as important to know the outcome of one’s current actions and decisions. If one doesn’t seem satisfied with the realistic interpretation of future, it can certainly help in altering current actions to direct towards a better future.

Dr. Sadao was a famous surgeon and scientist of Japan. He was a sympathetic man who remained loyal to his profession even in adverse situations. He lived in his ancestral square stone house in Japan, which was built upon rocks, above a narrow beach, on the Japanese coast.

Humanity and love are the only saving grace in this materialistic world governed by hatred and chaos. Our lives should be centered on harbouring these feelings in ourselves and in those around us. Keeping this in mind, if a doctor gets an opportunity to save a distressed and wounded person, he should definitely help him. People consider doctors next to God. Even their profession asks them to help all patients, regardless of caste, race, religion, or nationality. Thus, keeping humanity superior to anything else in life, the war prisoner should definitely be saved. (The above answer is only a sample provided for students’ reference. It is strongly recommended that students prepare the answer on their own.)

Dr Sadao, on humanitarian grounds as well as considering it his professional duty, tended a wounded war prisoner which was officially a serious crime. However, he did not get punished for this offence as it was never revealed to anyone, except his wife, loyal but timid servants, and a General who was too self-obsessed with his own treatment that he would never let the doctor leave him.

Dr Sadao and Hana found an unconscious wounded war prisoner who posed a huge threat to their own safety. However, Dr Sadao decided to go with his gut feeling and operate on him. He saved his life even though it was for the time being. Though half-heartedly, both took good care of the patient’s health and other needs. Hana even washed and fed him with her own hands. Although they knew that they would have to hand him over to the army sooner or later, they did their best to help the injured man.

The wounded American was in a very bad state and needed to be washed before being operated on. Hana did not want Dr Sadao to clean the dirty and unconscious prisoner, and so asked their servant, Yumi, to do so. However, Yumi defied her master’s order and opted out of it. As a result, Hana had no other option but to wash him herself. Although this act was impulsive and dipped in a sense of superiority over herservant, Yumi, she did it with sincerity.

Dr. Sadao gave the American prisoner of war a boat, a flashlight, food, and water. He told him to go to a nearby unguarded island. He should stay there till a Korean boat passed by and then escape taking refuge in it. He dressed him in Japanese clothes and wrapped a black cloth on his head. He asked him to signal him two flashes at the same instant the sun drops over the horizon. He asked him to signal him once if he was all right till the time he escaped in Korean boat. He helped the American soldier to escape and save his life. This act of Dr. Sadao was an act of humanism and compassion. As a doctor he had saved the life of a man without of any prejudice. Dr. Sadao had displayed himself as a man, full of compassion and humanity by this act.

Dr. Sadao’s father was a traditional man. He was a serious and stern man and a very concerned father. He never played with Dr. Sadao but had been very keen in providing the best to him. He was mainly concerned about Dr. Sadao’s education, that is why he sent Dr. Sadao to America to study. But at the same time, he wanted him to come back and serve his people. He had great respect for his culture and traditions.

Hana had ordered her maid Yumi to wash the American soldier. But Yumi bluntly refused to do so and said that she would have nothing to do with a white man. She even threatened to leave the job if forced to wash the American. So, Hana had to wash the wounded man herself.

The US Soldier was badly wounded. He had a deep wound which was to be operated upon immediately. Dr. Sadao needed some assistance at the time of operation. The most important task was to give anaesthesia to the patient at the time of operation so as to stop his movement. Dr. Sadao could not call anyone from outside as he had to keep the presence of US soldier in his house a secret. So, he asked Hana to help him during the operation and give anaesthesia to the patient.

The General was very ill, and he was being treated by Dr. Sadao. He needed an operation and for that he trusted only Dr. Sadao. Moreover, Dr. Sadao was doing a research to render ‘the wounds entirely clean’; that is why he was not sent abroad with the Japanese soldiers.

The General offered to send his private assassins to help Dr. Sadao in getting rid of the American. These assassins would kill the white man noiselessly and also dispose of his body.

The General trusted Dr. Sadao deeply. He did not want to be operated upon by anyone other than Dr. Sadao. The General believed that Germans were ruthless and quite cruel. So, he was afraid of being operated upon by them. He believed that the Americans valued life and had sentiments attached to it. So, he wanted to be treated by Dr. Sadao who was trained at America.

The second thing that happened on the seventh day was that a messenger came in official uniform to call on Dr. Sadao. When Hana saw the official, she got scared. She thought that the servants might have complained to the police about the white man and so the official had come to arrest Dr. Sadao.

Dr. Sadao needed assistance of Hana while operating. The wound was so deep that the man was to be given anaesthesia. Dr. Sadao asked Hana to help him by giving anaesthesia to the man during the operation. Though Hana had never done this before, she managed to help Dr. Sadao in his operation.

Dr. Sadao met Hana at a party at Professor Harley’s house in America. The Professor and his wife had invited their foreign students home. Students used to get bored there. Dr. Sadao was not in a mood to go to the Professor’s house that night because the rooms were very small, and the food was very bad. Moreover, Professor’s wife was voluble. But he went and there he met Hana. Had he not gone to the Professor’s house that night, he would have missed meeting and finally marrying Hana.

When Hana and Dr. Sadao saw the American soldier, they were in a dilemma. They were very loyal to their country and did not want to save the enemy. They wanted to hand him over to the police. But the man was wounded and in a pitiable state. Thus, the doctor inside Dr. Sadao urged him to save his life. Humanity rose above patriotism and they thought of first treating him and then handing him over to the police.

It was at the American professor’s house that Dr. Sadao met Hana for the first time. The professor and his wife, in order to show their kindness to the foreign students, had invited them to their house. Though Dr. Sadao did not want to go there, he went and there he met Hana who was a firstyear student.

Dr. Sadao was a skilled surgeon and a famous scientist. His excellence in his professional field was evident from the fact that the General had full faith in him as regards his health. Dr. Sadao was devoted to his work and to the cause of the needy. When he saw the American soldier in a wounded condition, he was torn between the natural human instinct to save his life and treat him or as a patriot hand him over to the police. Dr. Sadao saved the life of the man as per his professional ethics as he could not leave a person to die. It was his duty to save the life of a person as a doctor. At this point of time, when Dr. Sadao saw this dying man, his spirit of humanity surpassed everything else and so he saved one life irrespective of any colour, caste, or creed.

प्रश्नानुवाद → यह वाक्य संशोधित करें - "नगरेण परितः क्षेत्राणि सन्ति" (नगर से चारों ओर खेत हैं।)

स्पष्टीकरण → 

दिये गये विकल्पों में नगरं परितः क्षेत्राणि सन्ति अर्थात् नगर के चारों ओर बहुत क्षेत्र है। सही उत्तर है।

• संस्कृत व्याकरण में यदि किसी पद विशेष (अव्यय​) के योग में विशिष्ट विभक्ति का प्रयोग करते हैं तो उसे "उपपद विभक्ति" कहते हैं। कभी-कभी कारक चिन्हों के अनुसार विभक्ति न लगकर, कुछ विशेष अर्थों या अव्ययों के योग में जो विभक्ति होती है, वह उपपद विभक्ति है।
• यहाँ नगर के चारों ओर खेत है। कारक चिन्ह के अनुसार षष्ठी होनी चाहिए। किन्तु परितः अव्यय पद के योग में यहाँ द्वितीया विभक्ति लगेगी।
• परितः अर्थात् चारों ओर​। "अभितःपरितःसमयानिकषाहाप्रतियोगेषु च दृश्यते" इस उक्ति के अनुसार परितः, अभितः, समया, निकषा इन अव्ययों के योग में द्वितीया विभक्ति का प्रयोग होता है।

  • उदाहरण → ग्रामं परितः नदी वहति। (गाँव के चारों ओर नदी बहती है।)

  • लंकां परितः समुद्रः अस्ति। (लंका के चारों ओर समुद्र है।)

  • देवालयं परितः वनम् अस्ति। (देवालय के चारों ओर वन है।)

• प्रस्तुत नियम को देखते हुए यह समझा जा सकता है कि, उपरोक्त वाक्य में नगर प्रातिपदिक की तृतीया विभक्ति - नगरेण योजित है जो अनुचित है। नगर प्रातिपदिक की द्वितीया विभक्ति - नगरं योजित होनी चाहिए।

अतः स्पष्ट होता है कि नगरं परितः क्षेत्राणि सन्ति अर्थात् नगर के चारों ओर बहुत क्षेत्र है यह उत्तर उचित है।

अन्य विकल्प →  

• नगरस्य परितः क्षेत्राणि सन्ति → इस वाक्य में षष्ठी विभक्ति प्रयुक्त है।
• नगरात् परितः क्षेत्राणि सन्ति → इस वाक्य में पंचमी विभक्ति प्रयुक्त है।
• नगराय परितः क्षेत्राणि सन्ति → इस वाक्य में चतुर्थी विभक्ति प्रयुक्त है। (ये तीनों ही विकल्प अनुचित है।)
