The mother sent her away because she did not want a second girl.

माँ ने उसे विदा कर दिया क्योंकि वह एक और लड़की नहीं चाहती थी।

It looked like a sliced pomegranate.

यह टुकड़े किए हुए अनार की भाँति दिखाई देता था।

They gave her an injection to kill her.

उन्होंने उसे मारने के लिए इंजेक्शन दिया।

The unwanted girl is addressing the mother. She wants to talk to her mother who got her killed for being a girl.

न चाही गई लड़की माँ को संबोधित कर रही है। वह अपनी माँ से बात करना चाहती है जिसने उसे इसलिए मेरवा दिया क्योंकि वह एक लड़की थी।

She heard the sounds of the running traffic outside, the melting snow and the angry wind.

उसने बाहर दौड़ते हुए यातायात की आवाज सुनी, कुपित होती हुई हवा और पिघलती बर्फ की आवाज सुनी।

There are two characters in the poem, the mother and her unborn girl child who is killed by doctors with her mother’s consent. The girl wonders that her mother got ready so easily to get her killed as soon as the doctor told her, I would be a girl’. The girl could hear the happenings outside. She felt the world was a loveless place for her as no one liked to touch her not even her mother. She was cut into pieces like a pomegranate. The mother put on her green sari and went away. Still, she hopes her mother would listen to her requests to look for her.

इस कविता में दो पात्र हैं, माँ तथा उसकी अजन्मी लड़की जिसे डॉक्टरों द्वारा माँ की सहमति से मार दिया गया। लड़की को आश्चर्य होता है कि उसकी माँ इतनी आसानी से उसे मरवाने को तैयार हो गयी जब डॉक्टर ने उसे बताया कि ‘मैं एक लड़की होऊँगी।’ लड़की मरने से पूर्व बाहर की घटनाओं को सुन सकती थी। लड़की को ऐसा लगा कि यह दुनिया एक प्रेम से विहीन स्थान था जहाँ कोई भी उसे छूना नहीं चाहता था, उसकी माँ भी नहीं। उसे अनार की भाँति टुकड़ों में काट डाला गया। माँ ने अपनी हरे रंग की साड़ी पहनी और चली गयी। फिर भी वह (मृत लड़की) अपेक्षा करती है कि उसकी माँ उसकी प्रार्थनाओं को सुनेगी तथा उसकी तलाश करेगी।

Everyone smiled to show that the act of killing the girl was successfully completed.

प्रत्येक व्यक्ति इसलिए मुस्कराया कि वह दिखा सकता कि लड़की को मारने का कार्य सफलतापूर्वक पूरा कर लिया गया था।

She put on her grass-green saree and did her hair and went away as if nothing had happened.

उसने घास के समान हरे रंग की साड़ी पहनी, बाल ठीक किए और वहाँ से इस तरह चल दी जैसे कुछ हुआ ही न हो।

The poem is addressed to the girl’s mother.

इस कविता को लड़की की माँ को संबोधित किया गया है।

The poet does not like the city life. The pavements are dull and grey. There is chaos all around. But there is nature’s beauty all around in Innisfree. It is a dream place for the poet which exists in reality. There is a perfect harmony on the island between the plants and the weather.

At first glance it does appear that men invent machines because they are lazy. But this is afar from the truth. Machines take a long time to be invented- there goes behind them the patient study, investigation and labour of a dedicated team of scientists and research assistants. Gould a lazy man have done this? In fact, Machines have been invented by man to perform his work with grater efficiency.

Here are a few Indian idioms reflected in the text. Seed of a donkey

• Na – सोडियम
• C – कार्बन
• Br – ब्रोमीन
• Mn – मैग्नीज
• Ag – सिल्वर
• Au – गोल्ड
• Ba – बेरियम
• Ca – कैल्सियम
• Mg – मैगनीशियम

सही विकल्प है (अ) नाइट्रिक अम्ल

रासायनिक तत्वों के प्रतीक का उपयोग करने से हमें रासायनिक अभिक्रिया दर्शाने में आसानी होती है। जिससे यह पता चलता है कि अभिक्रिया में तत्व के कितने अणु या परमाणु सम्मिलित हैं।

अम्ल एवं क्षारक की पहचान करने के लिए हम विशेष प्रकार के पदार्थों का उपयोग कर सकते हैं जो सूचक कहलाते हैं। इन सूचकों को अम्लीय या क्षारीय पदार्थों के विलयन में मिलाने पर इनका रंग बदल जाता है। नीले तथा लाल रंग वाला लिटमस पत्र तथा गुड़हल की पंखुड़ियाँ प्राकृतिक रूप से पाए जाने वाले सूचक हैं। नीला लिटमस पेपर अम्ल में डुबोने पर लाल हो जाता है और लाल लिटमस पत्र क्षारक-विलयन में डुबोने पर नीला हो जाता है। इसी प्रकार गुड़हल की पंखुड़ियाँ अम्लीय विलयनों का गहरा गुलाबी और क्षारीय विलयनों को हरा कर देती है।

अम्ल और क्षार की पारस्परिक क्रिया द्वारा लवण तथा पानी का बनना उदासीनीकरण क्रिया है।

वह पदार्थ जो स्वाद में खट्टे होते हैं, अम्ल कहलाते हैं। अम्ल वे यौगिक हैं जो कि-

• पानी में घुलकर H⁺ आयन देते हैं।
• नीले लिट्मस को लाल कर देते हैं।
• क्षारों से क्रिया करके लवण तथा पानी बनाते हैं।
  जैसे- सल्फ्यूरिक अम्ल (H₂SO₄), हाइड्रोक्लोरिक अम्ल (HCl) तथा नाइट्रिक अम्ल (HNO₃) आदि।

H₂ का प्रयोग हाइड्रोजन के एक अणु को दर्शाने के लिए होता है, जबकि 2H का प्रयोग हाइड्रोजन के दो परमाणुओं को दर्शाने के लिए होता है।

(iii) A is true but R is false.

CH_4(g) + 2O_2(g) → CO_2(g) + 2H₂O₍₁₎ 

1 mole = 16 g of CH₄ gives 2 moles of H₂O i.e., 2 × 18 = 36 g of H₂O.

(iii) A is false but R is true.

As the solid has same value of refractive index along all directions, it is isotropic and hence amorphous. Being an amorphous solid, it would not show a clean cleavage when cut with a knife. Instead, it would break into pieces with irregular surfaces.

(i) p-orbitals can have 6 electrons.

(ii) d-orbitals can have 10 electrons.

The work function of wood is much higher than the energy of a photon emitted from the bulb. Hence photo electric emission is not possible.

The uncertainty in position decreases but uncertainty in velocity or momentum increases if the wave length of photon is short.

The uncertainty in momentum will increase while the uncertainty in position will decrease.

A unit cell is characterized by following six parameters: 

(i) The dimensions of the unit cell along the three edges. These are represented by a, b and c. The edges may or may not be mutually perpendicular. 

(ii) The angles between the edges. These are represented by α, β and γ. The angle α is. between b and c, β is between a and c and γ is between a and b.

In molten state, ionic solids dissociate to give free ions and hence can conduct electricity. 

However, in the solid state, as the ions are not free but remain held together by strong electrostatic forces of attraction, they cannot conduct electricity in the solid state.

(i) Very low value of electrical conductivity in the molten state.

(i) Valence band overlaps with conduction band.

(ii) The gap between valence band and conduction band is negligible.

(iv) Valence band may remain partially filled.

(ii) Silicon doped with an electron rich impurity is an n-type semiconductor.

(iii) Delocalised electrons increase the conductivity of doped silicon.

(i) Electron will move towards the positvely charged plate through electron holes.

(ii) Holes will appear to be moving towards the negatively charged plate.

Quantity demanded is that quantity of a commodity which a consumer is willing and able to buy at a particular price and a given point of time.

A short term (run) is a time period in which a producer cannot change factors of production. Hence in this period all the factors of production such as plant, heavy machinery, building of a factory, etc. remain fixed.

Market Demand refers to total demand by all the buyers of a commodity in the market.

When a product price increases, expenditure on the commodity will not increase in the situation when e_D > 1 (elasticity of demand is greater than unity). It will increase only in situation when e_D < 1. In a situation when e_D = 1, expenditure will remain constant, even when prices rise.

The Average Revenue curve shows the Average Revenue of a producer by selling of commodity.

Marginal Cost (MC_n) = Tc_n – Tc_(n-1), Here, n = no. of units produced and Tc = Total cost.

In a short period (run), the production may increase, decrease or become zero i.e. no production, but the cost would remain same. Such a type of cost is called the fixed cost. Fixed cost is also known as overhead cost. The fixed cost curve is parallel to X-axis.

When production increases the Total Fixed Cost (TFC) gets distributed among more units and so Average Fixed Cost decreases with increase in production.

Correct option is (C) Parallel to X-axis

Correct option is (B) Variable cost

Correct option is (A) Perfect Competition

Demand Schedule is a table which expresses the relationship between different quantities of a commodity demanded at different prices during a given period of time.

It is a graphic presentation of the inverse relationship between price and quantity demanded of a commodity.
