Explanation

Statement 1 is incorrect: The Infant Mortality Rate (IMR) accounts for the deaths of infants within the first year of life, not just within a month after birth. The mortality during the neonatal period (first 28 days) is a subset of infant mortality.

Statement 2 is incorrect: Infant Mortality Rate is defined as the number of infant deaths (under 1 year of age) per 1,000 live births in a given year, not per 100 live births.

Explanation

Population density is measured as the number of people living per square kilometer. Below is a table summarizing key demographic data from the three censuses:

Census Year Population Density (persons/sq km) Annual Exponential Growth Rate (%) 1951 117 1.25 2001 324 1.93 2011 382 ~1.64

Statement 1 is incorrect: In 1951, the density was about 117 persons/sq km. By 2001, it had risen to 324 persons/sq km. Although this is a substantial increase, calculating the multiplication factor shows: = × Factor 2.77 This means the density increased by roughly 2.77 times--which is less than three times. For additional context, the 2011 census reported a further increase to 382 persons/sq km, confirming a continuing but moderate increase.

Statement 2 is incorrect: The annual growth rate (exponential) of India’s population has not doubled during this period. The growth rate was highest during the 1971 Census but gradually declined thereafter, indicating no doubling of the growth rate between 1951 and 2001. The annual exponential growth rate is the average rate at which the population increases each year. The annual growth rate in 1951 was about 1.25%, and by 2001 it had risen to 1.93%. While this represents an increase, it is not a doubling of the rate. In fact, when we compare 1.25% and 1.93%, the rate has increased by a factor of about: × 1.93 1.54 1.25 In other words, it has increased by roughly 54%, not 100% (which would be doubling). Moreover, the trend into the 2011 census shows the growth rate has moderated to approximately 1.64% per annum (derived from a decadal growth of 17.7%), reinforcing that there has been no doubling.

Explanation

According to World Bank data, among the given South Asian countries, India has the highest population density. In 2008, its density was approximately 406. In comparison, Sri Lanka has population density roughly around 329, Pakistan about 246, and Nepal is around 208 persons per square kilometer.

Explanation

Sub-atomic particles are particles that are smaller than an atom. They are the basic building blocks of atoms. They are primarily categorized into two groups: elementary particles which are indivisible, and composite particles which are combinations of elementary particles.

Option (b) is correct: In the year 2008, the organization that conducted a complex scientific experiment in which sub-atomic particles were accelerated to nearly the speed of light was the European Organization for Nuclear Research (CERN). CERN operates the Large Hadron Collider (LHC), where particles are accelerated to extremely high speeds to explore fundamental physics. The experiment helps in understanding the Standard Model of Particle Physics exploring dark matter and studying the properties of fundamental forces.
