Concept: Shifting cultivation is a traditional farming method practiced mainly in tropical forest regions of Asia, Africa, and South America. It is characterized by the technique known as “slash and burn.” In this method, farmers first cut down (slash) the natural vegetation of a forest area and then burn the cleared vegetation. The ash produced from burning acts as a natural fertilizer, enriching the soil with nutrients for crop cultivation. After cultivating the land for a few years, the soil fertility decreases. Farmers then leave the land fallow and move to another area, repeating the same process. Hence, the cultivation shifts from one place to another, giving this method its name.
Step 1: Understanding the "slash and burn" process.
The method involves the following steps:

• Vegetation and trees are cut down (slashed).
• The cut vegetation is burned.
• Ash from the burned plants provides nutrients to the soil.
• Crops are cultivated for a few years.
• When soil fertility decreases, farmers move to a new area.

This agricultural method is commonly practiced by tribal communities.
Step 2: Examples of shifting cultivation in different regions.
Shifting cultivation is known by different names in different parts of the world:

• Jhum – North-East India
• Milpa – Mexico and Central America
• Ladang – Indonesia and Malaysia
• Chena – Sri Lanka

Step 3: Evaluating the options.

• Plantation Farming: Large-scale farming of crops like tea, coffee, rubber, etc.
• Intensive Farming: Farming with high inputs of labor and capital on small land areas.
• Shifting Cultivation: Uses the slash and burn technique. (Correct)
• Mixed Farming: Combination of crop cultivation and livestock rearing.

Therefore, the correct answer is:

Concept: Literacy rate refers to the percentage of people in a population who are able to read and write with understanding. In India, literacy statistics are collected during the national population census conducted every ten years. According to the 2011 Census of India, Kerala recorded the highest literacy rate among all Indian states. The state has consistently maintained high educational standards due to strong social development policies, widespread school infrastructure, and public awareness about education. The literacy rate of Kerala in the 2011 Census was approximately: This means that nearly 94 out of every 100 people in Kerala aged seven years and above were literate.
Step 1: Understanding literacy rate measurement.
In the Indian census, a person aged 7 years or above who can both read and write with understanding in any language is considered literate. The literacy rate is calculated using the formula:
Step 2: Identifying the state with the highest literacy rate.
Among Indian states, Kerala stands out due to:

• Strong emphasis on education since the early 20th century.
• High investment in public schooling.
• Effective literacy campaigns and social reforms.
• High female literacy rates.

Because of these factors, Kerala achieved the highest literacy rate in India in the 2011 Census.
Step 3: Evaluating the given options.

• Tamil Nadu: High literacy rate but lower than Kerala.
• Kerala: Highest literacy rate in India (93.91%).
• Maharashtra: Moderately high literacy but not the highest.
• Himachal Pradesh: Good literacy rate but still below Kerala.

Thus, the correct answer is:

Concept: The Demographic Transition Model (DTM) explains how population growth changes over time as a country develops economically and socially. It describes the transition from high birth and death rates to low birth and death rates. The model is generally divided into four stages, each representing a different pattern of population growth.

• Stage I – High Stationary Stage: Both birth rate and death rate are very high. Population growth is slow due to frequent diseases, poor healthcare, and limited food supply.
• Stage II – Early Expanding Stage: Death rates begin to fall rapidly due to improvements in medical facilities, sanitation, and food production. Birth rates remain high, leading to rapid population growth.
• Stage III – Late Expanding Stage: Birth rates begin to decline because of urbanization, improved education, family planning, and changing social values. Population growth starts slowing down.
• Stage IV – Low Stationary Stage: Both birth rates and death rates become low. Population growth becomes stable or very slow.

Countries with advanced economies and better healthcare systems usually fall into Stage IV.
Step 1: Understanding when both birth and death rates are low.
In the early stages of demographic transition:

• Birth rates remain high.
• Death rates gradually decline.

However, in the later stage of development, improvements in education, healthcare, and family planning reduce birth rates as well.
Step 2: Identifying the stage with low birth and death rates.
In Stage IV (Low Stationary Stage):

• Birth rate is low.
• Death rate is low.
• Population growth becomes stable or very slow.

Examples of countries in this stage include many developed nations such as those in Western Europe and North America.
Step 3: Evaluating the options.

• Stage I: Both birth and death rates are high.
• Stage II: Birth rate high, death rate declining.
• Stage III: Birth rate declining but not yet very low.
• Stage IV: Both birth and death rates are low.

Therefore, the correct answer is:
