False. 

Correct : ‘4 o’clock showers’ are caused by convection currents.

False. 

Correct : Arise in temperature causes more evaporation while a fall in temperature results in condensation.

1. To visit the Eastern Ghats

2. The geographical magic of the Eastern Ghats and the frequent appearance of lambasing in both the print and electronic media

3. The beauty of the valleys

4. The Kirandul Passenger

5. They took their breakfast.

1 mole of H₂ at STP occupy 22.4 dm³ 

1 mole of H₂ = 22.4 dm³ =6.022 x 10²³ molecules 

22.4 dm³ of hydrogen contain molecules = 6.022 x 10²³ 

1 dm³ of hydrogen contain molecules = 6.022X10²³ /22.4 = 2.69 x 10²² molecules

The ratio of molecules between 1 mole of H₂O and 1 mole of sucrose (C₁₂ H₂₂ O₁₁) are 1:1.

1. The Olympic Games were held in London in 1948. 

2. Being inhospitable is a sign of bad culture. 

3. He was forced to spend the night in the open.

“If the captain of our team chose more than one fast bowler, we would have won the game.

The response of his father: If you had scored the highest marks, you would have got a seat in the college you wanted.

Had it rained, the farmers could grow crops.

(a) gnarled and beautiful

No, he was not afraid but it was his practice.

1 – e

2 – c

3 – b

Shaking his hand.

c) Don Anselmo

Rio en Medio

Don Anselmo had the most of what time.

Don Anselmo took the possession of the house from his mother.

His coat was old, green and faded.

When the storyteller said “these Americans are Buena gent”, we can think that he was speaking Spanish.

c)  reading books

a. No, the old man wouldn’t raise the rate,

b. Yes, the storyteller offers more.

Don means Spanish little of respect much like sir in English.

He carried a cane, it was only the skeleton of a worn-out Umbrella.

(i) orchard

(ii) gazelle

(iii) Charlie Chaplin

(iv) Janitor

(v) Senator Catron

(vi) Prune

(vii) Preliminary

(viii) A very large farm

(ix) descendants

The unusual and attractive especially in an old fashioned way quaint.

A branch of a tree with twisted hard lumps gnarled.

Don Anselmo was generous. He refused to accept more money for his property. He loved children and planted a tree for every child. Americans were generous, they won’t quarrel with the old man though they had legal right to own the trees.

1. b) he wanted to see why the crowd had gathered

2. b) a path at the side of the road for people to walk

3. b) let the crowd know that his monkey was dead

4. The oldman began to weep to get the sympathy from people and expect more money from them.

5. Robert was smiling to himself and went on his way and amazed at the man’s audacity.

The storyteller or Americans convinced the persons individually. The descendants have agreed to sell their trees to them. It was a long procedure to convince everyone. At last they have agreed and sold the trees to Americ Answer: The problem was solved but it took a long time.

Usually any person get offer for more money he would accepted. But Don Anselmo’s reaction was not at all expected. Though it is a fair offer, after surveying, the land rate was double. Double the land, double the money. But once he agreed to sell his land for twelve hundred dollars, he should stick on his words. It was not expected.

We agree with Don Anselmo’s argument when he sold his property. Though it is unusual and far way from reality, according to him it was correct. He was a man of principles, he thought that it was right to stand on his words. So he refused to take more than the amount agreed upon. In the second incident also he was right because the tree was planted in the name of new born child. All the trees belong to children only. He had no right to sell them though it is unusual. But here the story teller’s saying is in vogue. 

The population of India was estimated to be 920 million in 1994. Over-population upsets all plans of development and causes poverty and unemployment. So either population is controlled or people would remain poor forever. Voluntary family planning helps population control in India.

There are four principal biological systems of the earth. These systems are fisheries, forests, grasslands and croplands. However, due to the increasing demand of human beings to such an ‘unsustainable’ extent, the productivity of these systems is being hampered. The excessive demand results in deterioration and depletion of these resources. A country where protein is consumed on a large scale, overfishing is common, which leads to the collapse of fisheries in that area. Grasslands have been turned into deserts and production of crops is decreasing. The forests are destroyed in large proportions to obtain firewood. Depletion of tropical forests has also led to the extinction of several species.

In many areas of the world, earth’s biological systems have reached an unsustainable level. They have reached a point where their productivity has been damaged. This is because of the excessive pressure exerted by man on them.

The new world vision is a holistic view. ,It is also an ecological view. It considers the world as ah integrated whole-a global village, rather than a separated or isolated collection of parts. This emerging new world vision has introduced the era of responsibility.

Scientists have arranged a list of about 1.4 million living species. The number of unlisted species is much more. It varies from three to a hundred million according to various estimates. These still remain unknown and unidentified.

The notice signifies that there is depletion of resources and deterioration of environment. Man is responsible for this and his own survival is threatened.

It is well-known that industries are a main source of causing environmental pollution. There will be a great change in the preservation of environment if the industrialists become consicous of their responsibilities and become environment friendly. Thus, Industry has to play a very important role in the new era of responsibility.

The author, Nani Palkhivala, refers to the ‘Green Movement’. It has becomes very popular among the people of all countries. It started nearly twenty-five-years ago but it has gripped the imagination of the entire human race completely and quite rapidly.

Mr Edgar S. Woolard was the chairman of a famous industrial concern-Du Pont. Five years ago, he declared himself to be the company’s ‘Chief Environmental Officer’. He said that their continued existence as a leading manufacturer required that they excelled in environmental performance.

(c) Exponent

Explanation: 2 is the rational number which is the base here and n is the power of 2. Hence, it is an exponent.

Using laws of exponents ,a^m × aⁿ = a^(m+n)

And , a^m ÷ aⁿ = a^(m-n)

We have , (2⁵ ÷ 2⁸) = 2^(5-8) = 2^-3

Now , 2^-3 × 2^–7= 2^(-3)+(-7) = 2^-10

∴ (2⁵ ÷ 2⁸) × 2^–7= 2^-10

(c) 3¹¹

Explanation: By the law of exponents, we know,

a^m/aⁿ=a^m-n

Hence, 3⁵ ÷ 3^-6 = 3^5-(-6) = 3¹¹

The above statement is false.

We know that , 2 × 10^-2 

= 2 × 1/10² 

= 2 × 1/100 

= 2/100 

= 0.02

The above statement is false.

Because , 5^-2

= 1/5² 

= 1/25 ≠ 25. …….(using laws of exponents i.e.a^-m= 1/a^m)

Correct option is (a) touch

Multiplicative is inverse or reciprocal of number.

⇒ Multiplicative inverse of a/b is b/a.

⇒ So, the multiplicative inverse of 10¹⁰ will 1/10¹⁰

∴ Multiplicative inverse of 10¹⁰ =10^-10

Hence, multiplicative factor of 10¹⁰ is 10^–10

False

LHS = (-4)^-2 = 1/(-4)² = 1/4²

RHS = (4)^-2 = 1/(4)² = 1/4²

LHS equal to RHS

Therefore these numbers are same and not multiplicative inverse.

(c) 10¹⁰⁰

Explanation: By the law of exponent we know: a^-n = 1/aⁿ.

So, 10^-100 = 1/10¹⁰⁰

The multiplicative inverse for any integer a is 1/a, such that;

a x 1/a = 1

Hence, the multiplicative inverse for 1/10¹⁰⁰ is 10¹⁰⁰

as, 1/10¹⁰⁰ x 10¹⁰⁰ = 1

False

⇒ (-6)⁰ = 1
