How would you describe the behavior of the Maharaja’s minions towards him? Do you find them truly sincere towards him or are they driven by fear when they obey him?

Answer»

The Maharaja’s minions could not give the right advice to the king because the despotic and foolish king was driven by fear of death. The minions either flattered him or remained mute. They were afraid lest they should lose their own life at the king’s behest. Only the dewan was conscious of the resentment that was brewing in the kingdom because of the king’s arbitrary decisions. He showed some sense in arranging the hundredth tiger that the king could kill. He had hoped that this way the king would get rid of his fear and his atrocities would cease. Unfortunately, the tiger did not die at the hands of the king. It was impossible for the minions to make the superstitious king see reason. They feared that any attempt to do so would invite punishment, even death.

We should try to regulate interest rates prevailing among farmers, weaker sections of society and poor villagers. How can we control it?

Answer»

1. A government and monetary authorities fix the rate of interest which is based on bank rate fixed by the RBI and consequent interest rates are charged by the commercial banks. 

2. In this regard we have regional rural banks being set up in rural areas to benefit the rural artisans, small and marginal labourers and weaker sections of the society. 

3. They provide credit assistance at concessional lending rates. 

4. However, weaker sections of society including poor farmers and villagers pay very high rate of interest which they pay to the moneylenders or zamindars. 

5. Therefore, for reducing rate of interest for such people, some necessary steps should be taken such as promoting cooperative societies etc.

Negligence often causes huge losses. How did the negligence of the prison officers prove to be a boon for Evans? 

Answer»

Many instances of negligence on the part of the prison officers contributed to Evans escape. First lapse on the part of the police and prison authorities was regarding Mr McLeery. He was to invigilate. They didn’t verify his identity. A fake McLeery impersonated the real McLeery. Secondly, Jackson’s compassion allowed Evans to wear his hat. It was a big lapse on his part. Then again Stephens didn’t report another significant irregularity to the authorities. Evans was allowed to wrap a grey blanket around him. Similarly, the authorities never knew that the German teacher was none other than a close friend of Evans. The last but the most glaring lapse was on the part of the governor himself. The silent prison officer who handcuffed the recaptured was actually Evans’s accomplice. So were the two men who accompanied them. The governor was outwitted again.

What made Cuss interview the stranger? What kind of interview was it and what did come out of it?

Answer»

The interview was not intended fairly by Cuss, the general practitioner. He had a keen desire to know about the stranger. He approached the stranger on the pretext of collecting subscription for the nurse fund. This way he hoped to interact with the stranger and know the secret of his bandaged face. The stranger sensed his motive and with an apparently armless sleeve pinched Cuss’ nose, thus scaring him to death. It turned out to be an extraordinary, an unusual and a nightmarish kind of experience for Cuss as the things he noticed and felt could hardly be rationalized. Cuss fled straight to punting and related his incredible experience to him. Thus out of professional envy he managed to only infuriate the stranger rather than knowing something valuable about him. It was an insincere of interview on the part of Cuss and proved fruitless in the end.

Therefore, in such a situation for helping farmers in case of drought the government should fix a price lower than the market price (which is also known as price ceiling) and in case of the surplus production the government should fix a price higher than the market price (which is also known as price floor). 

3. Surplus or shortages should be met by the government from its buffer stock operations through Public Distribution System (PDS) such as ration shops or fair price shops.

(a) In a pond there were 200 frogs. 40 more were born in the year. Calculate the birth rate of the population.(b) Population in terms of number is not always a necessary parameter to measure population density. Justify with two examples.

Answer»

(a) Birth rate = No of individuals born Total no of individuals = 40 /200 = 0.5 frogs per year. 

(b) Number is not always a necessary parameter to measure population density. 

Example: 

1. If there are 200 Parthenium plants but only a single huge banyan tree with a large canopy, the population density of banyan is low relative to that of Parthenium which amounts to underestimating the enormous role of the Banyan in that community. In such cases, the per cent cover or biomass is a more meaningful measure of the population size.

2. In a dense laboratory culture of a microbial population in a petri dish, the total number of microbes is again not an easily adoptable measure because population is huge, counting is impossible and time-consuming.

Answer»

Ratio of H, P and S is 4 : 3 : 3

H’s Gain = 3/10 X 20 /100 = 3 /50 

H’s new share = H’s old share + H’s Gain

= 4/10 + 3/50 = 23/50

S’s Gain = 3/10 X 80 /100 = 12 /50

S’s new share = S’s old share + S’s Gain

= 3/10 + 12/50 = 27/50

New Profit sharing Ratio of H and S is 23 : 27

Describe the Modern history.

Answer»

Modern history conventionally includes the period from the French Revolution to the most recent decades. The growth of disciplinary power thus coincided with new individual and collective freedoms; a widespread belief in progress was accompanied by an equally prominent obsession with the past; European predominance soon led to anti-colonial nationalism. Such tensions and paradoxes make studying modern history fascinating in its own right as well as invaluable for understanding present-day culture, society and politics.

What is tooth enamel chemically? State the condition when it starts corroding. What happens when food particles left in the mouth after eating degrades? Why do doctors suggest use of tooth powder/toothpaste to prevent tooth decay?OrTooth enamel is one of the hardest substances in our body. How does it undergo damage due to the eating of chocolates and sweets? What should we do to prevent it?

Answer»

White tooth enamel is calcium phosphate which is very hard. It gets affected when the pH of our mouth falls below 5.5. The bacteria present in our mouth breaks down the food particles into acids which damage our teeth by corroding them.

To prevent the tooth decay, cleaning of the mouth thoroughly after eating with tooth powder/paste, which is basic in nature and neutralizes the excess of acid, is a must.
