Q-20 Passage- based questionAcids, bases and salts are the three main categories of chemical compounds. These have certain definite properties which distinguish one class from the other.The acids are sour in taste while bases are bitter in taste. Tasting a substance is not a good way of finding out if it is an acid or a bases. Acids and bases can be better distinguished with the help of indicator. Litmus, a purple dye is extracted from the lichen plant. Some indicators are prepared artificially, for example , methyl orange and phenolphthalein. Given below is a table of indicators and their color change in acidific and basic medium.Indicator Color in Acid Color in alkaliLitmus Red BlueMethyl Orange Pinkish red yellowPhenolphthalein colorless Pink

(i) Give two examples each of natural and artificial indicators.(ii) An aqueous solution turns red litmus solution blue. Excess addition of which

solution would reverse the change- ammonium hydroxide solution or hydrochloric acid?

(iii) What will be the change in color when few drops of Phenolphthalein is added to a solution having pH 8.5?

(iv) What is Universal indicator?

Q1)Red Cross: How Hope Evolved

On June 24, 1859, Emperors Napoleon III and Franz Joseph I engaged in

the Battle of Solferino, commanding a combined total of about 270,000

troops onto the field for a single day of battle. Nearly 40,000 were either

dead, injured, or missing, many of whom were simply left to die on the

battlefield. Later, spectators crowded the fields, looking for loved ones,

searching for items they could sell, or simply taking in the horrors of the

battle .A Swiss businessman and social activist Jean Henri Dunant, who

was traveling in Solferino witnessed all this.

Jean Henri Dunantwitnessed the atrocities of war as well as the countries

not prepared or equipped to ease the suffering of those who had been

injured in the Battle of Solferino. Dunant organized a group of volunteers to

help bring water and food to the injured, to assist with medical treatment, or

write letters to the families of those who were dying and he urged the public

to create an organization which would assist the wounded, regardless of

which side they fought for during times of war. After that moment, he wrote

the book, A Memory of Solferino, which urged the public to create an

organization which would assist the wounded, regardless of which side

they fought for during times of war. His writing inspired countless others to

rally behind him in the creation of the International Federation of the Red

Cross.

The modern-day Red Cross began by devoting itself largely to disaster

relief and epidemic treatment. This effort continues to this day. One of the

easiest ways you can help the Red Cross is to make sure you are able to

donate blood and make an appointment at the Red Cross website. But,

donating blood isn't the only way you can help out—the Red Cross also

encourages donating your time if you can. This is what the Red Cross

wants everyone to know.

On the basis of your reading of the passage given above, answer the

following questions

a)How many soldiers fought in the battle of Solferino on June 24?

i. 270,000 ii. 40,000 iii. 230,000 iv. 23,000

I. Dunant organised a camp of volunteers.

II. Emperor Napoleon III and Franz Joseph I fought a battle.

III. The book ‘A Memory of Solferino was written.

IV. Dunant travelled in Solferino.

(i) IV, III, II, I (ii) I, II, III, IV (iii) II, I, IV, III (iv) II, IV, I, III

c) The writer of 'A Memory of Solferino’ was:

i. Emperor Napoleon III

ii. Franz Joseph I

iii. Jean Henri Dunant

iv. International Red Cross

d) The modern day Red Cross does not deal with:

i. Blood donation

ii. Disaster Relief

iii. Epidemic Treatment

iv. Writing a book

e) The most appropriate sub-heading to para 2 of the passage is:

i. How International Federation of Red Cross Evolved!

ii. Functions of Red Cross

iii. The Contributions of Jean Henri Dunant

iv. The Battle of Solferino

f) The aid provided by Dunant’s volunteers during the battle of Solferino

was:

I. to help bring water and food to the injured

II. to assist with medical treatment

III. to write a book

IV. to give relief in epidemic

(i) I and III (ii) III and IV (iii) I and II (iv) II and III

g) You can donate your blood and your _________ to Red Cross.

h) Jean Henri Dunant participated in the war.( True/ False)

Q2 Read the passage carefully

Road to Success

1. The Road to success is not straight; there is a curve called failure, a loop

called confusion, speed bumps called friends, caution lights called family,

and you will have flats called jobs. But, if you have a spare called

determination, an engine called perseverance, insurance called faith, and a

driver called God, you will make it to a place called success!

2. In spite of all our planning and preparation, unexpected challenges are

certain to arise. The bumps in the road are unavoidable, but you’ll never

get to your destination if you aren’t willing to drive over them. The

difference between a disaster and triumph lies in whether or not you’re

prepared and willing to weather the storm. If you’re ready, those bumps will

become stepping-stones.

3. The key thing to realize is that working harder is same as working

smarter. How do you work smarter? You just need to have the right skills.

People want improved circumstances and better life without an improved

self. They want victory without paying the price or making efforts. It really

cannot happen without the other. Any improvements that have not been

generated by improving yourself are superficial and short-lived. If you want

to have a better future, you have to change yourself. Stop worrying about

the various challenges that will come your way. Just believe in yourself and

use them as stepping-stones.

4. “Success” is getting whatever you want out of life without violating the

rights of others.” It is not an accident. Success is the result of our

attitude and our attitude is a choice. Hence success is a matter of choice

and not chance.

5. Today success represents a holistic and positive attitude to life. Attitude

is everything. Success is not restricted within some kind of brick and mortar

premises. It assumes the individuality of a complete act executed with

perfection; material achievements do not define life. We don’t remember

sports stars for the products they endorse but the spirit of achievement

they represent. In the abundance of positive attitude underline the grandeur

of a truly rewarding rich life.

6. Success can be measured from two standpoints—the external and the

internal. Externally it is the measure of a job well done and recognition.

Internally it the feeling of achievement and wholeness derived from the

completion of a task or fulfillment of desire.

2.1 On the basis of your reading of the above extract, answer the following

questions in 30-40 words each:

(a) What qualities lead one to the place called success?

(b) What is the difference between disaster and triumph?

(c) How can one have a better future?

(d) Describe two ways to measure success.

2.2 On the basis of your reading of the above extract, answer the following:

(a) The synonym of ‘victory’ as given in paragraph 2 is ____________

(i) Planning (ii) Preparation (iii) Triumph (iv) Challenges

(b) The synonym of ‘surplus’ as given in paragraph 5 is ______________

(c) The antonym of ‘Defeat’ as given in paragraph 6 is _____________

(i) Recognition (ii) Achievement (iii) Completion (iv) Success

(d) The antonym of ‘deep’ as given in Paragraph 3 is ____________

Section B: Writing & Grammar
