• The earliest kind of print technology was developed in China, Japan and Korea. This was a system of hand printing.
• From AD 594 onwards, books in China were printed by rubbing paper – also invented there – against the inked surface of woodblocks.
• As both sides of the thin, porous sheet could not be printed, the traditional Chinese ‘accordion book’ was folded and stitched at the side.
• Superbly skilled craftsmen could duplicate, with remarkable accuracy, the beauty of calligraphy.
• The imperial state in China was, for a very long time, the major producer of printed material. China possessed a huge bureaucratic system which recruited its personnel through civil service examinations.
• Textbooks for this examination were printed in vast numbers under the sponsorship of the imperial state. From the sixteenth century, the number of examination candidates went up and that increased the volume of print.

The Varuna naval exercise is a biennial exercise between the Indian Navy and the French Navy. The 21st edition of the exercise, Varuna-23, was held in the Arabian Sea in September 2023. Phase II of the exercise was held from September 6 to 9, 2023.

Herodotus is known as the "Father of History" because he was the first historian to systematically collect and record historical events. He travelled extensively throughout the Mediterranean region, interviewing people from all walks of life to learn about their history and culture. His magnum opus, the Histories, is a comprehensive account of the Greco-Persian Wars and the history of the surrounding region.

The Directive Principles are listed in  Part IV of the Indian Constitution and it clearly states that it is the duty of the State to apply these principles in the process of law-making.

• There are mainly three categories of these principles – Socialist Directives, Gandhian Directives, and Liberal Intellectual Directives.

Important Points

• DPSP – Gandhian Principles
  • These principles are based on the Gandhian ideology used to represent the program of reconstruction enunciated by Gandhi during the national movement. Under various articles, they direct the state to:
  • Article 40 Organise village panchayats and endow them with necessary powers and authority to enable them to function as units of self-government
  • Article 43 Promote cottage industries on an individual or co-operation basis in rural areas
  • Article 43B Promote voluntary formation, autonomous functioning, democratic control, and professional management of cooperative societies
  • Article 46 Promote the educational and economic interests of SCs, STs, and other weaker sections of the society and protect them from social injustice and exploitation
  • Article 47 Prohibit the consumption of intoxicating drinks and drugs which are injurious to health.
  • Article 48 Prohibit the slaughter of cows, calves, and other milch and draught cattle and improve their breeds.

• DPSP – Socialistic Principles
  • They are the principles that aim at providing social and economic justice and set the path towards the welfare state.
  • Article 38 Promote the welfare of the people by securing a social order through justice—social, economic and political and to minimise inequalities in income, status, facilities and opportunities.
  • Article 39 Secure citizens: Right to adequate means of livelihood for all citizens
  • Article 39A Promote equal justice and free legal aid to the poor
  • Article 41 In cases of unemployment, old age, sickness and disablement, secure citizens: Right to work, Right to education, Right to public assistance.
  • Article 42 Make provision for just and humane conditions of work and maternity relief.
  • Article 43 Secure a living wage, a decent standard of living and social and cultural opportunities for all workers.
  • Article 43A Take steps to secure the participation of workers in the management of industries.
  • Article 47 Raise the level of nutrition and the standard of living of people and to improve public health.
• DPSP – Liberal-Intellectual Principles
  • Article 44 Secure for all citizens a uniform civil code throughout the country
  • Article 45 Provide early childhood care and education for all children until they complete the age of six years
  • Article 48 Organise agriculture and animal husbandry on modern and scientific lines
  • Article 48A To protect and improve the environment and to safeguard forests and wildlife
  • Article 49 Protect monuments, places and objects of artistic or historic interest which are declared to be of national importance
  • Article 50 Separate the judiciary from the executive in the public services of the State
  • Article 51 Promote international peace and security and maintain just and honourable relations between nations

Thus, we can say that Freedom of Business and Religion is not a Directive Principle.

Teachers, nowadays, are promoting seminars as these are helpful in boosting students' self-confidence. Besides, they also help all the students (both listeners and the student delivering the seminar) in preparing a difficult topic easily.
A seminar is a group meeting led by an expert that focusses on a specific topic or discipline. Attending a seminar has numerous benefits, including improving communication skills, gaining expert knowledge, networking with others and renewing motivation and confidence.

In the triarchic theory, three types of intelligence proposed by Robert Sternberg are: Analytical, Creative and Practical.

UNESCO is a United Nations' organization that uses education, culture and science as a medium to promote international collaboration and lead to peace and security in the world.

NEP 2020 aims to achieve a Gross Enrollment Ratio (GER) of 50% in higher education by 2035.

The compounds with each doubly bonded carbon attached to two different groups (like Cab=Cab, Cab=Ccd) exhibit geometrical isomerism i.e., cis and trans forms. The geometrical isomerism arises due to restricted rotation of double bond.

However, even though there is restricted rotation for triple bond, alkynes do not exhibit geometrical isomerism, since the triply bonded carbons are attached to one group each only.

A pi-bond is a type of covalent bond in which the internuclear axes of the atoms are parallel to each other and for side-wise overlapping. The bond formed here is perpendicular to the internuclear axes.

(C—Cl) bond has (C=Cl) double bond character, thus it is stable.

Benzyl carbocation is stable due to resonance, hence (C—Cl) bond is cleaved easily.

Glucose solution is one molal. Thus, 1000 g water (solvent) has glucose = one mole = 180 g

Total mass of solution = 1000 +180 = 1180 g

1180 g of solution has glucose = 180 g 

∴ 1000 g of solution has glucose =
180 x 1000/1180 = 152.5 ≈ 153g  

The correct answer is Option B.
The optically active hydrocarbon X is 3-methyl-1-pentene CH₂=CH−CH(CH₃)CH₂CH_3​. On catalytic hydrogenation, it forms 3-methyl pentane CH₃CH₂CH(CH₃)CH₂CH₃, which is optically inactive.

Number of chiral centers = 2

the k is halved while the A is doubled. Hence R remain 50 Ω.

(c)

AB = a, AC = a

BC² = AB² + AC² =2a²

Radius =r

then BC = CD + DE + EB = r + 2r + r = 4r 

∴ 16r² = 2a²

∆S = nCplnT₂/T₁ + nRlnP₁/P₂
Since pressure is constant, so the second term will be zero.
Or ∆S = 3×7/2×8.314×2.303×log(1000/400)
= 80.42 JK^-1

 (a,b,c)

(a) r = radius, a = edge length 

then for hcp, r  = 

Volume of one spherical atom 

Number of atoms in one unit cell = 4

∴ Volume of four atoms  

Volume of cube = a³

∴ Packing efficiency =

Thus, correct.

(b) In hep coordination number = 12, six at the diagonal and six at the edge length thus, correct.

(c) A tetrahedral void is formed when a sphere of a second layer is above the void of the first layer or vice-versa thus, correct.

The correct answer is option B
During the polymerization of ethylene, one mole of ethylene breaks i.e. one C = C double bond breaks and the two CH₂- groups are linked with C-C single bonds thus forming three single bonds. 

But in the whole unit of polymer, number of single C-C bonds formed/mole of ethylene is 2.

Energy due to formation of 2 C-C single bonds = 2 X 331 = 662 kJ/mol. 

 Energy due to dissociation of 1  C = C double bond = 590 kJ/mol. 

Thus, the enthalpy of polymerisation per mole of ethylene at 298 K = (590-662) = -72 kJ/mol

CaCO₃.Mg(OH)₂ can be precipitate out in order to remove temporary hardness.

H₂O₂ behaves as a bleaching agent because it breaks the chemical bonds of the chromophores

Com pounds having oxidising and reducing nature in given reaction are said to have oxidation-reduction duality. Such compounds are said to undergo disproportionation reaction.

(This is called Cannizzaro reaction.)

Note Such compounds have O.N. of the affected atoms intermediate of oxidation part and reduction part
