Which of the following titles best describes the passage?

An intellectual is one who is enlightened; and being an enlightened person, he has to give light to others who are in need of it. In every society, we find intellectuals such as philosophers, scientists, scholars, writers, and critics; and they, as enlightened men, have a great responsibility towards society. In a society, all cannot be intellectuals. If a time comes when all are intellectuals it would be a blessed time indeed; but intellectuals have the great responsibility of guiding others on to the right path. If today we have our civilisation and culture, if we have orders and security in life, and if our life is better that that of our primitive ancestors, it is because the intellectuals, from time to time, have been guiding humanity on the path of felicity and amity. Therefore, the intellectual should come out of his ivory tower and try to elevate others to his level."

What does the phrase 'ivory tower' in the extract denote?

English speaking people have never been really homogeneous in their use of the English language. Today, if you travel extensively in the British Isles, you notice differences in pronunciation and vocabulary from shire and shire, or even if your ear is good enough, from town to town. In London alone you can find tremendous diversity in the varieties of English. In the United States, likewise, the language differs somewhat from place to place and from one social ""class"" to another. Many New Yorkers don't pronounce words as Chicagoans do, and in Denver people don't sound like those in Chicago. In some parts of the Southwest, Spanish influence shows up in the vocabulary; elsewhere, Germans and others have affected the English language."

The word "tremendous" means-

An intellectual is one who is enlightened; and being an enlightened person, he has to give light to others who are in need of it. In every society, we find intellectuals such as philosophers, scientists, scholars, writers, and critics; and they, as enlightened men, have a great responsibility towards society. In a society, all cannot be intellectuals. If a time comes when all are intellectuals it would be a blessed time indeed; but intellectuals have the great responsibility of guiding others on to the right path. If today we have our civilisation and culture, if we have orders and security in life, and if our life is better that that of our primitive ancestors, it is because the intellectuals, from time to time, have been guiding humanity on the path of felicity and amity. Therefore, the intellectual should come out of his ivory tower and try to elevate others to his level."

Who are intellectuals according to the extract?

After two periods of captaincy cut short by his constant companion, namely injury, Mashrafe bin Mortaza was handed over the baton once again in 2014 to lead the national side in both ODI and T-205 The journey of Mortaza, called the ""Narail Express"", as a captain coincided with the glorious transformation of the Bangladesh Tigers from the perennial minnows to a major cricketing power. His charismatic leadership and unflinching patriotism helped Bangladesh turn into a strong unit and qualify to the quarter finals for the first time in their history in 2015 World Cup Cricket. That too by knocking out England, the birth-land of the game and one of the favourites for the title. This sprit is induced by the brave skipper who led the Bangladesh team to beat top-class opponents like Pakistan, India and South Africa and lose narrowly to England in subsequent bilateral home series. He inspired the Tigers in qualifying to the semi-finals of 2017 edition of Champions Trophy by trumping the strong outfit of New Zealand. Moreover, Bangladesh under Mashrafe's fearless leadership fought neck to neck with Sri Lanka on the latter's home turf in 2017. The Tigers won more matches than lose under his shrewd stewardship, thus making the most successful of Bangladesh captains."
