The question asks for the founding date of the International Labour Organization (ILO). This requires knowledge of historical dates related to international organizations.
Correct Option: D) 28 June 1919
The question asks to identify the 'father of modern botany'. This requires knowledge of key figures in the history of biology and their specific contributions to the field of botany.
C) Carl Linnaeus is widely regarded as the 'father of modern botany' due to his groundbreaking work in developing the binomial nomenclature system for classifying organisms, including plants. His system, detailed in his work Species Plantarum (1753), provided a standardized way to name and categorize species, which is still fundamental to botany and biology today.
The question asks about the historical figure who introduced the practice of 'sijda' in India. This requires knowledge of the Delhi Sultanate period and the administrative/court practices of its rulers.
D) Ghiyas-ud-din Balban introduced the practice of 'sijda' (prostration) and 'paibos' (kissing the monarch's feet) in his court. He did this to enhance the prestige and power of the Sultan and to instill a sense of awe and submission among his nobles and subjects, drawing inspiration from Persian court traditions.
To find the mean of the first two observations, we first need to determine the value of 'x'. We can do this by using the given mean of all five observations. Once 'x' is found, we can calculate the first two observations and then their mean.
C) 21.5 is the correct mean of the first two observations.
The question asks about the number of phases in which the Lok Sabha election was conducted in 2019. This is a factual question related to Indian electoral history and general knowledge about the Lok Sabha elections.
Correct Option: D) The 2019 Lok Sabha elections were indeed held in seven phases, making this the correct answer.
Read the given statements, labelled Assertion (A) and Reason (R), and select the most appropriate option with respect to them.
'A': Carbon dioxide is not always a pollutant.
'R': Plants require carbon monoxide for growth that they get from carbon dioxide.
Statement 'A' is true but statement 'R' is false.
Both statements 'A' and 'R' are false.
Both statements 'A' and 'R' are true but 'R' is not the correct explanation of 'A'.
Both statements 'A' and 'R' are true and 'R' is the correct explanation of 'A'.
The question asks us to evaluate two statements, an Assertion (A) and a Reason (R), regarding carbon dioxide and its role. We need to determine the truthfulness of each statement and whether the Reason correctly explains the Assertion.
Carbon dioxide (\(\text{CO}_2\)) is a naturally occurring gas essential for life on Earth. Plants use \(\text{CO}_2\) during photosynthesis to produce food and oxygen. In this context, it is not a pollutant but a vital component of the ecosystem. However, excessive amounts of \(\text{CO}_2\) released into the atmosphere due to human activities (like burning fossil fuels) contribute to the greenhouse effect and climate change, making it a pollutant in that context. Therefore, the statement that it is not always a pollutant is true.
Plants require carbon dioxide (\(\text{CO}_2\)) for photosynthesis, not carbon monoxide (\(\text{CO}\)). Carbon monoxide is a toxic gas and is harmful to both plants and animals. Plants absorb \(\text{CO}_2\) from the atmosphere, not \(\text{CO}\), for their growth processes. Therefore, this statement is false.
Since statement (A) is true and statement (R) is false, there is no question of (R) being a correct or incorrect explanation for (A).
A) Statement 'A' is true but statement 'R' is false. This option correctly identifies that Assertion (A) is true (carbon dioxide is essential for plants and thus not always a pollutant) and Reason (R) is false (plants use carbon dioxide, not carbon monoxide, for growth).
The question asks us to find the relationship between the first pair of words and apply the same relationship to the second pair. The relationship is typically based on action, characteristic, or classification.
Correct Option: D) Flutter. Butterflies are known for their distinctive way of flying, which involves light, rapid, and irregular movements of their wings. This action is best described as "fluttering". Therefore, "Flutter" is to "Butterfly" as "Charge" is to "Bull".
Select the Venn diagram that best represents the relationship between the given set of classes. Wrestlers, Boxers, Fighters
To determine the best Venn diagram representation for the classes Wrestlers, Boxers, and Fighters, we need to understand their relationships. Wrestlers and Boxers are specific types of Fighters, meaning they are subsets of the broader category Fighters.
Correct Option: A) The diagram shows two smaller circles inside a larger circle, accurately representing Wrestlers and Boxers as subsets of Fighters.
The question asks for the year in which the Chauri Chaura incident took place. This is a direct factual question related to Indian history, specifically the Non-Cooperation Movement.
A) 1922: The Chauri Chaura incident occurred on February 4, 1922, in Chauri Chaura, Gorakhpur district, United Provinces (modern-day Uttar Pradesh).
The problem provides the cost of a certain number of pencils and pens. We need to find the cost of a different, but proportionally related, number of pencils and pens. This can be solved by identifying the scaling factor between the given quantities and applying it to the total cost.
The cost of 10 pencils and 12 pens is ₹150.
\[ 10 \text{ Pencils} + 12 \text{ Pens} = \text{₹}150 \]We need to find the cost of 30 pencils and 36 pens.
Compare the number of pencils and pens in the given and required scenarios:
Since both the number of pencils and the number of pens are multiplied by the same factor (3), the total cost will also be multiplied by this factor.
Multiply the initial total cost by the scaling factor (3).
\[ \text{New Cost} = \text{Initial Cost} \times 3 \]\[ \text{New Cost} = \text{₹}150 \times 3 \]\[ \text{New Cost} = \text{₹}450 \]B) ₹450 is the correct answer because the quantities of both pencils and pens are scaled by a factor of 3, so the total cost also scales by the same factor.
