The author went to Bridport to meet Mrs Jim Macpherson and deliver Jim’s letter to her.

(c) Silk , Answer is correct

Caterpillar may cause irritation, skin allergy and transfer diseases.

C. To deliver the letter to Connie Macpherson.

C. the candles that she used for light in place of electricity.

‘Pungi’ a musical instrument was banned because of its shrill and unpleasant sound. But a nai modified and perfected it and s played it for the first time in Shah’s chamber, thus it came to be known as ‘Shehnai’.

Connie or Mrs Macpherson was 10 is years old. When the author took Jim’s letter to her in a nursing home, she became very excited. Her eyes lit up and she mistook the author for her husband. She kissed his s cheek. She said that she had been reading his letter every day. But she wanted to hear his voice. She had made a Christmas cake j; also for him as he had promised to come home. She thought that he was back home. She called his presence at home as the best Christmas present for her in the world.

Connie thought that the visitor was her own husband, Jim Macpherson.

England and Germany were at war with each other. Both the armies were in their respective trenches, either waiting to shoot or hying to avoid being shot at. But on Christmas, a strange development took ‘ place. The German soldiers came out of their; hiding places and called out ‘Happy Christmas’. They were unarmed and they waved a white; flag. The British soldiers led by captain Jim; Macpherson were all too eager to celebrate ‘ the festival together.

War means bloodshed, hate and ‘ destruction. It shows the animalism in man. Even the animals fight for some sound reason. But nations go to war to settle some petty! dispute or in the name of religion. War solves no problem. Understanding alone can end differences. All religions condemn greed ‘l and bloody quarrels. Let us learn this great lesson from history.

That sentence is; I sat down beside her.’ This he did in response to her request and the request was made to Jim!
If the writer wanted to reveal his identity this was the moment, but he let It pass.

25 December 1919

It’s Christmas today, but the town looks very much different from what I had imagined. It has been ravaged by war. Buildings are in ruins and there is graveyard silence. My own house is in ruins as it was hit by a bomb. The events of war have taken a toll on civilians as well as soldiers. I hate the fighting instinct in us and curse the war-makers (mongers). Can’t we live in peace like brothers?

It was the year 1930. India was a British colony. People of India wanted to end this subjugation. They started fighting for freedom. A young, newly-married doctor was implicated in a conspiracy case. He was sent s to Black Waters (Kalapani). It was a group of Islands in the Bay of Bengal.

Many freedom fighters and revolutionaries were sent there for life. They were put in Cellular Jail for a few years. They were subjected to torture. The doctor was hanged. But his wife kept ‘ waiting for the return of her husband. She; grew old. However, her hope and faith did not fade.

August 10, 1991

Dear Smith,

I am in a dilemma. It seems to be insolvable. I, therefore, seek your help in making a decision. You know I had purchased an old desk. Inside it got a box containing an old letter. It was written by Jim, a British soldier, to; his wife during world war I. I decided to deliver that letter to Mrs Jim at Brid port.

I reached her house. She is 101 years old now. When I gave her the letter, her eyes lit up. She thought I was her long lost husband Jim, who had come home to keep his promise. She was excited and she kissed me. She didn’t listen to what I tried to tell; her about my identity. I don’t know whether or not I should tell t who I am. I only walked away from her quickly.

1. nothing

2. distant

3. terrible

4. happened

5. armies

6. together

Mrs Macpherson lived alone after her husband (Jim Macpherson) went to join the British army during the First World War. She spent many lovely years after the war. One day her house caught fire. But she was saved by the firemen. From then on she had been in a mu-sing home. She had grown extremely old and couldn’t walk on herself. And her life got confined to a wheelchair.

1. who

2. out

3. in

4. and

6. on

Given that,

Side of rhombus = 14 cm

Altitude of rhombus = 16 cm

Since rhombus is a parallelogram, therefore

Area of parallelogram = base × altitude

Area of parallelogram = 14 × 16 = 224 cm²

यहाँ C = 12 pF = 12 x 10^-12 फैरड; V = 50 वोल्ट 

अत: स्थिर वैद्युत ऊर्जा 

U =  CV² 

= 1/2 x (12 x 10^-12) x (50)² जूल 

= 1.50 x 10^-8 जूल

1/C_s = 1/20 + 1/30 = 1/12

⇒ C_s = 12 µF

MOET- Multiple Ovulation Embryo Transfer Technology

Multiple Ovulation Embryo Transfer (MOET) technology can be used to improve production of hybrids. This technique produces 8-10 eggs at a time and the genetic mother is only available for superovulation. By this technique, herd size can be increased in a short time.

1. Bio fortification.

2. It is the breeding of crop with higher level of vitamin& Minerals or higher protein & healthier fats. It is the most practical means to improve public health.

3. IARI, New Delhi, released vitamin enriched carrots, Spinach, pumkin vitamin c enriched bitter gourd, mustard,tomato& calcium enriched spinach & protein enriched beans – Broad lablab, French beans & garden peas.

1. MOET is multiple ovulation embryo transfer technology. It is the controlled breeding method. It is done to improve the chances of successful production of hybrids.

2. steps used for herd improvement:

• Cow is given hormones with FSH-like activity
• To induce follicular maturation and super ovulation It produce 6-8 eggs/cycle.
• This animal is then mated with an elite bull or artificially inseminated.
• The fertilised eggs at 8-32 cells stages, are removed and transferred to surrogate mother.

(a) Mexico’s international Wheat and Maize Improvement Centre

1. The main steps of plant breeding are Collection of variability Evaluation and selection of parents Cross hybridisation among the selected parents Selection and testing of superior recombinants Testing, release and commercialisation of new cultivars

2. Green revolution

The main steps of plant breeding are

• Collection of variability
• Evaluation and selection of parents:
• Cross hybridisation among the selected parents: 
• Selection and testing of superior recombinants: 
• Testing, release and commercialisation of new cultivars.

(a) Wheat, rice and maize

1. It takes 3-10 kg of grain to produce 1 kg of meat using animal farming. That is why cereals demand increases.

2. Spirulina can be easily grown on starch, molasses etc. and can make food which is rich in proteins, minerals, fats, carbohydrates and vitamins. This could be a good alternative for dealing with the problem of malnutrition.

The refraction of light caused by the earth’s atmosphere is called atmospheric refraction. It is caused due to the varying optical densities of different layers of earth’s atmosphere. 

Correct Answer is: (a, d)

Correct Answer is: (a) B = 2B₀, v = 2v_0, (b) B = 2B₀, v = v₀ 

Pitch = (2π m/QB) vcos θ.

Here, m, Q and θ are constant.

∴ pitch = k (v/B), where k = constant

Initially, d = k (v₀ B₀) .

Correct Answer is: (b) only on y

Energy of the particle = work done by the electric field = electric field X displacement in the direction of the electric field

Correct Answer is: (b, c)

The electric field exerts a force opposite to the component of motion along the x-axis.

Correct Answer is: (a) m^1/2 ,(b) Q^1/2 ,(c) V^1/2 

Energy = QV = p²/2m 

or p = (2mQV)^1/2.

Correct Answer is: (a) E, (b) s, (c) l^2, (d) u^-2

As there is no horizontal force, the horizontal component of the velocity remains constant = u.

Time of transit between the plates = t = l/u.

In the vertical direction, F = QE, a = F/m = QE/m.

∴ displacement = 1/2 at² = 1/2 . QE/m (l²/u²) = 1/2 Es (l²/u²).

Correct Answer is: (a) r_a = r_p < r_d 

√(2mE) = BQE, where E = energy. Here, B and E are the same for all three particles.

∴ r ∝ √m/Q.

Let m_p = m, m_d = 2m, m_a = 4m

Q_p = e, Q_d = e, Q_a = 2e, k = constant.

r_p = k √(m/e), e_d = k √(2m/e), r_a = k √ (4m/2e) = k √m/e =r_p

∴ r_a = r_p < r_d.

Correct Answer is: (d) zero

The magnetic field due to the ring is along its axis. Therefore, there is no force of interaction between the ring and the straight conductor lying along its axis.

Correct Answer is: (b) tan θ = 4d/l

The motion is identical to that of a projectile, with the constant electrical force acting as the gravitational force. Treat l as the horizontal range and, d as the maximum height.

Correct Answer is: (b, c, & d)
