  • Question 2/10
    2.5 / -0.83

    Directions For Questions

    Direction: Read the following passage and answer the question given below. Your answer should be based on the passages only.

    Climate change is a long-term change in the average weather patterns that have come to define Earth's local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term. Increased heat, drought, and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.

    Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats.

  • Question 3/10
    2.5 / -0.83

    44% of the total population of a village is below 20 years old and 25% of them are graduate. If the total population of the village is 2400 what are the Number of person who are under 20 years old but not graduate?

    Solutions

    Given:

    Total population in village = 2400

    Percentage of population whose age is below 20 year = 44%

    Percentage graduate = 25%

    Number of person whose age is below 20 year old = 2400 × 44% = 2400 × 44/100 = 1056

    Number of graduate person = (1056 × 25%) = 264

    ∴ Number of person who are not graduate but under 20 year old = (1056 - 264) = 792

    In the sum

    1® + 1®9 + ®® + ®9 + 9® = ®17

    for which digit does the symbol ® stand?

    Solutions

    1) 12 + 129 + 22 + 29 + 92 = 217

    LHS = 12 + 129 + 22 + 29 + 92 = 284 ≠ RHS

    2) 15 + 159 + 55 + 59 + 95 = 517

    LHS = 15 + 159 + 55 + 59 + 95 = 383 ≠ RHS

    3) 13 + 139 + 33 + 39 + 93 = 317

    LHS = 13 + 139 + 33 + 39 + 93 = 317 = RHS

    4) 14 + 149 + 44 + 49 + 94 = 417

  • Question 6/10
    2.5 / -0.83

    Directions For Questions

    Direction: Read the following passage and answer the question given below. Your answer should be based on the passages only.

    Even some animals depend on fire. The sole food source for the endangered Karner blue butterfly caterpillar (Lycaeides melissa samuelis) is a plant called wild lupine (Lupine perennis). Wild lupine requires fire to maintain an ecosystem balance in which it can thrive. Without fire, the lupines do not flourish, and the caterpillars cannot consume enough food to undergo metamorphosis and become butterflies. In this way, healthier, post-burn plant populations generally have broad food web effects that trickle up to the foragers and other animals in the ecosystem.

    Similarly, animals that use pine trees for their homes benefit from the germinating powers of fire. Several plants actually require fire to move along their life cycles. For example, seeds from many pine tree species are enclosed in pine cones that are covered in pitch, which must be melted by fire for the seeds to be released. Other trees, plants, and flowers, like certain types of lilies, also require fire for seed germination.

  • Question 7/10
    2.5 / -0.83

    Directions For Questions

    Direction: Read the following passage and answer the question given below. Your answer should be based on the passages only.

    If the Earth were to stop spinning, gradually the oceans would migrate towards the poles from the equator. You could travel around the Earth on the equator and stay entirely on dry land—ignoring the freezing cold on the night side, and the searing heat on the dayside. At the Equator, the earth's rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.

    Which of the following is an assumption made in the passage?

    Solutions

    Let us note the following:

    An assumption is a fact that is accepted without any proof.

    It cannot be deduced directly from the passage.

    The author is trying to understand the effect if the earth stops spinning.

    Thus the author has by default accepted the rotation of earth without any proof.

    So, option (A)is the correct assumption.

    The option (C) finds a direct mention in the passage

    So, it is not an assumption.

    The option (B) sound more like a negative random conclusion.

    Therefore, option (B) is not an assumption.

    Therefore, the correct answer is 'The earth had been in rotation continuously since long'.

    Hence, the correct option is (A).

     

  • Question 8/10
    2.5 / -0.83

    In a village there are 300 people. They produce different crops, out of all people 190 people produce paddy, 160 people produce wheat and 100 people produce both paddy and wheat. Find the number of people who neither produce paddy nor wheat.

    Solutions

    Given:

    The total population of the village is 300.

    Out of all people, 190 people produce paddy, 160 people produce wheat and 100 people produce both paddy and wheat.

    Through this diagram, we can assume about the people associated with different crops

    Wheat(only) producers = 60, paddy(only) producers = 90 and Paddy and Wheat producers = 100

    Total people associated with production = 60 + 90 + 100

    ⇒ 250

    People not associated with anything = 300 - 250

    ⇒ 50

    ∴ There are 50 people who neither produce paddy nor wheat.

     

  • Question 9/10
    2.5 / -0.83

    Directions For Questions

    Direction: Read the following passage and answer the question given below. Your answer should be based on the passages only.

    The level of unemployment varies with economic conditions and other circumstances. The causes of unemployment include increased population, rapid technological change, lack of education or skills and rising costs lead to financial, social, and psychological problems. The personal and social costs of unemployment include severe financial hardship and poverty, debt, homelessness and housing stress, family tensions and breakdown, boredom, alienation, shame and stigma, increased social isolation, crime, erosion of confidence and self-esteem, the atrophying of work skills and ill-health. In Indi, one-third of the workforce is employed as casual labour while just 17 per cent of the people are working in the organized sector as salary earners, the 5th annual survey for 2015-16 showed. A recent Mckinsey Global Institute report suggests that India's GDP will need to grow at 8 to 8.5 percent annually over the next 10 years to create 90 million or nine crore non-farm jobs.

  • Question 10/10
    2.5 / -0.83

    Directions For Questions

    Direction: Read the following passage and answer the question that follows. The answer should be based on the passage only.

    First and foremost, making new friends requires stepping beyond your comfort zone and putting yourself out there. If you experience social anxiety or fear of rejection, try to confront your inner voice and adjust any negative assumptions you might have about how people will respond to you. A 1980s study published in the Journal of Personality and Social Psychology found that volunteers who believed that a person they were interacting with liked (or disliked) them began to act in ways that made this belief more likely to come true. This suggests that if you go into social situations with the confidence that most people will like you, it’s more likely that this will actually be the case. Remind yourself of your likeable qualities and be open to the possibilities.
