The rising era of Coalition government and regional politics has given rise to inter-relation between center and state governments. The word 'coalition' means a collective type that decides to work collectively jointly in an alliance to achieve a shared goal between two or more individuals, factions, governments, political parties, military forces, etc. Tolerance and in case of no single party rule makes it easier.

The official languages of Sri Lanka is Sinhalese. It is the Sinhalese people's native language, who total approximately 16 million. An additional 4 million speak Sinhalese as a second language. This language belongs to the Indo-European language family. Within that category, is part of the Indo-Aryan branch. It is written with the Sinhalese alphabet which descends from the ancient Indian Brahmi writing. Modern-Sinhalese is traced to the Dravidian language as well as Pali and the medieval version of Sinhalese. It has also borrowed words from Tamil, Portuguese, Dutch, and English. The Rodiya community within Sri Lanka speaks a dialect of Sinhalese called Rodiya. It is considered an indication of belonging to a lower-caste in the society.

In the belgium model of power sharing
1-The state governments are not subordinate to the central which means they are not answerable to them.
2-Many powers of the central are given to the states.
3-The Dutch and the French enjoy a majority over each other in the whoe nation and the capital respectively . Thus Both the communities have equal number of representatives in the central as well as the Brussels's government.
4-There is a third government known as the community government which is elected by people belonging to one language , irrespective of where they live. This government has the power on cultural matters.

Aruna Singh answered |
The Sri Lankan Tamils launched parties and struggles for the recognition of Tamil as an official language, for regional autonomy and equality of opportunity in securing education and jobs. But their demand for more autonomy to provinces populated by the Tamils was repeatedly denied. By 1980s several political organizations were formed demanding an independent Tamil Elam (state) in northern and eastern parts of Sri Lanka. The distrust between the two communities turned into widespread conflict. It soon turned into a Civil War.

Vikas Choudhury answered |
A coalition government is formed when two or more political parties join forces in order to create a majority. It's done in a bid to win an election under circumstances when the individual parties don't have nearly enough support to be elected by themselves, or following a "hung" election where there is no clear winner.
Other situations where a coalition may be formed is in times of war, economic crisis, or some other crisis where it's more important to work together than to follow normal political procedure.
Obviously, a coalition party has to compromise on certain issues, work together under circumstances where they normally wouldn't, and this can cause problems.
Some nay-sayers believe that such governments have a tendency to be fractious and prone to disharmony, because the individual parties hold differing beliefs and normally disagree on particular issues. At times, it's been known for polar opposite parties to come together as a coalition, and some argue that this is suboptimal and tends to add inertia to the political process.

Aditi Iyer answered |
The correct answer is option 'C', which states that 59 per cent of the country's total population who speaks Dutch lives in the Flemish region. Here is a detailed explanation of why this option is correct:
Flanders is the northern region of Belgium, and it is home to the majority of the country's Dutch-speaking population. Dutch is one of the three official languages of Belgium, along with French and German. The distribution of these languages is not uniform across the country, and there are three main linguistic regions in Belgium:
1. The Flemish Region: This region encompasses the provinces of Antwerp, Limburg, East Flanders, West Flanders, and Flemish Brabant. It is predominantly Dutch-speaking and home to about 6.5 million people, which is approximately 59 per cent of Belgium's population who speaks Dutch.
2. The Walloon Region: This region covers the provinces of Hainaut, Liège, Luxembourg, Namur, Walloon Brabant, and the French-speaking part of Brussels. It is predominantly French-speaking and home to about 3.6 million people.
3. The Brussels-Capital Region: This is a bilingual region that includes the City of Brussels and 18 surrounding municipalities. It is home to about 1.2 million people, and both French and Dutch are official languages.
Therefore, option 'C' is correct because it correctly identifies the Flemish region as the place where the majority of the Dutch-speaking population of Belgium lives.

Niharika Mehta answered |
Understanding Reproduction
Reproduction is a biological process that ensures the continuation of a species. It can be broadly classified into two types: asexual and sexual reproduction. The method of reproduction significantly influences the genetic diversity of the offspring.
Asexual Reproduction
- In asexual reproduction, a single organism produces offspring without the involvement of gametes (sex cells).
- The offspring are genetically identical to the parent, resulting in little to no variation.
- Common examples include binary fission in bacteria, budding in yeast, and vegetative propagation in plants.
Sexual Reproduction
- In contrast, sexual reproduction involves the fusion of male and female gametes, leading to the formation of a zygote.
- This process introduces genetic variation in offspring due to the combination of genes from two parents.
- Organisms can adapt more effectively to environmental changes due to this genetic diversity.
Why Sexual Reproduction Leads to More Variation
- Genetic Recombination: During meiosis, the process of gamete formation, genetic material is shuffled and recombined, resulting in unique genetic combinations.
- Mutations: Sexual reproduction allows for the introduction of new traits through mutations, which may be beneficial for adaptation.
- Selection Pressure: The variation produced enhances the chances of survival and reproduction in changing environments, as some offspring may possess advantageous traits.
In summary, sexual reproduction is the method that leads to greater variation in offspring compared to asexual reproduction, making option 'B' the correct answer. This genetic diversity is crucial for the evolution and adaptability of species.

The Concept of Heredity
Heredity refers to the biological process through which traits and characteristics are passed down from parents to their offspring. This fundamental concept is crucial in understanding genetics and how living organisms inherit various features.
Key Points about Heredity:
- Transfer of Genetic Information:
- Heredity involves the transmission of genes, which are units of heredity located on chromosomes.
- These genes carry information that determines physical traits, such as eye color, height, and susceptibility to certain diseases.
- Role of DNA:
- Deoxyribonucleic acid (DNA) is the molecule that contains the genetic blueprint for an organism.
- During reproduction, DNA from both parents combines, resulting in a unique genetic makeup for the offspring.
- Mendelian Inheritance:
- The principles of heredity were first systematically studied by Gregor Mendel in the 19th century.
- Mendel’s laws describe how traits are inherited through dominant and recessive alleles.
- Variability and Evolution:
- While heredity ensures that offspring resemble their parents, it also introduces variations due to mutations and recombination.
- This genetic diversity is essential for evolution and adaptation to changing environments.
Conclusion
Understanding heredity is crucial for fields such as medicine, agriculture, and evolutionary biology. It provides insights into how traits are inherited and can influence health and behavior in future generations. In summary, option 'B' accurately represents heredity as the transfer of characteristics from parents to offspring, highlighting its fundamental role in biology.

Understanding Mendel's F2 Generation
Mendel's experiments with pea plants laid the foundation for genetics, especially in understanding inheritance patterns.
Single Trait Inheritance
When studying a single trait, Mendel observed the inheritance of dominant and recessive alleles. In his experiments, he crossed homozygous parents:
- P Generation: One parent with two dominant alleles (AA) and another with two recessive alleles (aa).
- F1 Generation: All offspring (Aa) displayed the dominant trait.
F2 Generation Results
When F1 plants were self-fertilized, the F2 generation emerged, revealing a classic 3:1 phenotypic ratio of dominant to recessive traits:
- Phenotypic Ratio: 3 dominant (AA or Aa) : 1 recessive (aa)
However, when considering the genotypes:
- Genotypic Ratio: This includes:
- 1 homozygous dominant (AA)
- 2 heterozygous (Aa)
- 1 homozygous recessive (aa)
Thus, the genotypic ratio for the F2 generation is:
- 1 AA : 2 Aa : 1 aa
Correct Answer: 1:2:1
This corresponds to option 'B'. The 1:2:1 ratio illustrates the distribution of genotypes resulting from the segregation of alleles during meiosis.
Conclusion
Mendel's work exemplifies the foundational principles of genetic inheritance, with the F2 generation showcasing the predictable ratios of genotypes and phenotypes, crucial for understanding heredity.

**Background Information:**
Sri Lanka, formerly known as Ceylon, gained independence from British colonial rule in 1948. At the time, English was recognized as the official language, and it continued to be widely used in education, administration, and legal proceedings.
**The Official Language Act of 1956:**
In 1956, the Official Language Act, also known as the Sinhala Only Act, was passed in Sri Lanka. This act recognized Sinhala as the only official language of the country, replacing English. The act was primarily driven by nationalist sentiments and aimed to elevate the status of the Sinhala language and the majority Sinhalese community.
**Key Factors:**
Several factors contributed to the passage of the Official Language Act in 1956:
1. Nationalism and Identity: The act was driven by nationalist sentiments and a desire to promote the Sinhala language as a symbol of the country's identity. It was seen as a way to assert the dominance of the Sinhalese community.
2. Ethnic Divide: Sri Lanka has a diverse population, with the Sinhalese community comprising the majority and the Tamil community being the largest minority. The act further deepened the ethnic divide by marginalizing the Tamil language and community.
3. Political Motivations: The passage of the act was also politically motivated, with politicians from the majority Sinhalese community using language as a tool to gain support and consolidate their power.
**Implications and Controversies:**
The Official Language Act had significant implications for Sri Lankan society:
1. Marginalization of Tamils: The act marginalized the Tamil language and community, leading to increased tensions and disparities between the Sinhalese and Tamil communities. It further fueled ethnic tensions and grievances that eventually escalated into a decades-long civil war.
2. Discrimination and Language Barriers: The act also resulted in discrimination against Tamils in various spheres, such as employment, education, and access to government services. Language barriers hindered the participation and advancement of Tamils, leading to a sense of alienation and inequality.
3. Repeal and Language Reconciliation: In subsequent years, there were efforts to promote language reconciliation and address the grievances of the Tamil community. The 13th Amendment to the Sri Lankan Constitution in 1987 recognized both Sinhala and Tamil as official languages, aiming to promote equality and inclusivity.
**Conclusion:**
In 1956, the Official Language Act recognized Sinhala as the only official language of Sri Lanka, replacing English. This act had far-reaching implications for the country's linguistic and ethnic dynamics, deepening the divide between the Sinhalese and Tamil communities. The act was driven by nationalist sentiments, political motivations, and a desire to elevate the status of the Sinhala language and community. However, it also resulted in marginalization, discrimination, and inequalities for the Tamil community.

Variations during reproduction primarily occur through:
- Genetic Recombination: During sexual reproduction, chromosomes from both parents exchange genetic material, creating unique combinations in offspring.
- Mutations: Random changes in the DNA sequence can lead to new traits, introducing variations across generations.
These processes ensure diversity within a species, aiding in adaptation and survival. Genetic inheritance alone does not account for new variations, making option B the correct answer.

- Gregor Mendel, known as the father of genetics, studied the inheritance of traits in pea plants.
- He observed that when crossing two heterozygous parents (F1 generation) for a single trait, the F2 generation showed a 3:1 phenotypic ratio.
- This means 3 offspring displayed the dominant trait, while 1 displayed the recessive.
- This ratio results from the combination of alleles: 1 homozygous dominant (AA), 2 heterozygous (Aa), and 1 homozygous recessive (aa).
What is the main mechanism of sex determination in humans?- a)The temperature of fertilized eggs

- Chromosomes from Parents: Human sex determination is based on the chromosomes inherited from parents. Each parent contributes one sex chromosome.
- Chromosome Pairs: Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY).
- Role of Y Chromosome: The presence of a Y chromosome determines male development because it carries the SRY gene, which triggers male characteristics.
- Genetic Basis: The combination of these chromosomes at fertilization determines the sex of the offspring.

Significant Tension in Belgium: Ethnic Conflicts
During the 1950s and 1960s, Belgium faced significant tension primarily due to ethnic conflicts. The country is divided mainly between two linguistic groups: the Flemish, who speak Dutch, and the Walloons, who speak French.
Language as a Divider
- The division between the two groups is not merely linguistic but also cultural and political.
- The Flemish population, primarily in the northern region of Flanders, began to demand greater political autonomy and recognition of their language and culture.
- Conversely, the Walloons, concentrated in the southern region of Wallonia, felt threatened by the rising prominence of the Flemish language and culture.
Political Implications
- Tensions escalated as political representation became a contentious issue.
- Flemish demands for more power led to a sense of marginalization among the Walloons, contributing to a growing divide.
- The political landscape became polarized, with parties often aligning along linguistic lines, making consensus difficult.
Social and Economic Factors
- Ethnic conflicts also had social and economic repercussions.
- Flanders experienced economic growth, while Wallonia faced decline, leading to feelings of resentment and competition.
- This disparity fueled the narrative that each community was competing for limited resources and political power.
Conclusion
- The ethnic conflicts during this period were crucial in shaping Belgium’s political trajectory.
- These conflicts laid the groundwork for future reforms and the eventual establishment of a federal state, aimed at addressing the demands of both communities.
Understanding these ethnic tensions is vital to comprehending Belgium's complex socio-political landscape during the mid-20th century.
