The question asks about the transmission methods of the Zika virus. We need to evaluate two statements: one regarding mosquito transmission and another regarding sexual transmission. Knowledge about the epidemiology of Zika virus is essential to answer this question.
Correct Option: C) Both 1 and 2
The question asks for the average density of population in India. Population density is calculated by dividing the total population by the total land area. This is a factual question requiring knowledge of demographic statistics for India.
C) 440 People per square Km
While the 2011 Census reported India's population density as 382 people per square kilometer, current estimates (as of 2023-2024) place it closer to 430-440 people per square kilometer due to population growth. Option C, 440 people per square Km, is the most accurate representation of the current average population density in India among the given choices.
The question asks about the subject matter of two specific International Labour Organization (ILO) Conventions: 138 and 182. To answer this, one needs to have knowledge of key international labour standards and their respective convention numbers.
Correct Option: A) Child labour. Both ILO Convention 138 (Minimum Age Convention) and Convention 182 (Worst Forms of Child Labour Convention) are fundamental conventions specifically designed to combat and eliminate child labour in its various forms. India has ratified both these conventions.
Around 2010, the average density of population in the world was approximately:
45 persons per sq km
51 persons per sq km
85 persons per sq km
95 persons per sq km
The question asks for the approximate average population density of the world around 2010. Population density measures the number of people living per square kilometre of land area. To identify the correct option, we need to understand the concept and compare the given values with historical estimates.
Understand population density:
Population density is the average number of people living in a unit area, usually expressed as persons per square kilometre.
It is calculated using the formula:
\[ \text{Population Density}=\frac{\text{Total Population}}{\text{Land Area}} \]Understand the world population around 2010:
Around 2010, the world's population was approximately 6.9 billion people.
The population was distributed unevenly across continents, with densely populated regions in Asia and relatively sparsely populated regions in deserts, mountainous areas and polar regions.
Identify the approximate global population density:
Historical estimates place the world's population density in the low-to-mid 50s per square kilometre around 2010, depending on the land-area definition and dataset used.
Among the given options, 51 persons per square kilometre is the closest approximation.
Understand the significance of average population density:
Average population density represents the overall relationship between population and land area.
It does not mean that every region has the same population density. Some regions have extremely high population densities, while others have very low population densities.
Identify the correct answer:
Among the given options, 51 persons per square kilometre is the closest to the estimated world population density around 2010.
Therefore, Option B is the correct answer.
Correct Option: B) 51 persons per sq km — Around 2010, the world's average population density was approximately in the low-to-mid 50s per square kilometre. Among the given choices, 51 persons per square kilometre is the closest approximation. Hence, Option B is the correct answer.
A) 45 persons per sq km: This is incorrect because 45 persons per square kilometre is lower than the estimated global population density around 2010. It is more representative of an earlier period.
C) 85 persons per sq km: This is incorrect because 85 persons per square kilometre is substantially higher than the global average around 2010.
D) 95 persons per sq km: This is incorrect because 95 persons per square kilometre considerably exceeds the estimated world average for that period.
The question asks about the climate of the Sahara Desert. To answer this, one needs to recall general geographical knowledge about major desert regions, specifically the Sahara, and their characteristic climatic conditions.
Correct Option: A) Very Hot — The Sahara Desert is known for its extremely high daytime temperatures, making "Very Hot" the most accurate description of its climate.
| List I | List II |
| 1) Sahara Desert | a.) South Africa |
| 2) Nile | b.) Very Hot |
| 3) Diamond mines | c.) Egypt |
| 4) Cultural place | d.) Jerusalem |
To solve this matching question, we need to correctly associate each item in List I with its corresponding description or location in List II. We will go through each item in List I and find its most accurate match in List II.
Combining these matches, we get: 1-b, 2-c, 3-a, 4-d.
Correct Option: B) 1-b,2-c,3-a,4-d
