II. wild
III. herbivorous

Detailed Solution for CRPF Head Constable Mock Test - 8 - Question 21

Domesticated: (of an animal) tame and kept as a pet or on a farm
Herbivorous: (of an animal) feeding on plants
“Domesticated” and “herbivorous” animals would not attack people. Even if they attack for some
reason, they would not consider humans their ‘prey’.

Only the word “wild” fits perfectly in the blank. “Wild” animals would consider humans as ‘prey’ and
attack them too.
Hence, option B is the correct answer.

CRPF Head Constable Mock Test - 8 - Question 22

Which one best expresses the given sentence in Passive/Active Voice?

Has someone made all the necessary arrangements?

Detailed Solution for CRPF Head Constable Mock Test - 8 - Question 22

This sentence is in the active voice, with the subject "someone" performing the action of making the necessary arrangements. To convert it to the passive voice, the object of the verb (the necessary arrangements) becomes the subject of the sentence, and the verb is changed to its past participle form (been made). The preposition "by" is added to indicate who performed the action.

Option (c) correctly expresses the sentence in the passive voice. Option (a) and (b) are incorrect because they use incorrect word order, and option (d) is in the active voice, with the subject "one" performing the action.

CRPF Head Constable Mock Test - 8 - Question 23

Direction: The sentences given in the question, when properly sequenced, form a coherent paragraph. Each sentence is labeled with a letter. Choose the most logical order of sentences from the given choices to construct a coherent paragraph.

A. Not long after their victory, the Greeks began to think that they would never stack up to the glories of the past.

B. Throughout antiquity, those warriors, especially the Marathonomachai, who fought and defeated the Persian troops in the 490 BCE Battle of Marathon, would be revered as Athens’ Greatest Generation.

C. Even in the mid-fifth century BCE, Athenians were already looking back with longing.

D. A few decades earlier, Athenian citizen-soldiers had helped to rout the Persian invaders of Greece.

Detailed Solution for CRPF Head Constable Mock Test - 8 - Question 23

Sentence A refers to a “victory"?. What victory? Sentences B and D seem to provide an answer. Sentence B talks of the Greek warriors in the Battle of Marathon while sentence D is a more general statement about Athenian warriors routing Persian invaders. So, both sentences A and B are likely to follow D. Which of these sentences comes immediately after D? Sentence A states that not long after the victory, the Greeks already began to look back at it and think that they could never match this past glory. This does make sense when placed immediately after D. Now, consider sentence B. It talks of the Marathonomachai warriors who fought the war being regarded as Athens’ Greatest Generation. This too, looks like a good option to follow D. So, we need to look at some other clues to help us finalize the sentence order.

Sentences B and C make references to time. B talks of the 490 BCE war and C, of the mid- fifth century BCE (around 450 BCE). Note that in terms of timeline, B precedes C.

Now, C talks of Athenians “looking back with longing"?. To what? D provides an answer: a few decades earlier, Athenian citizen-soldiers had helped to rout the Persian invaders of Greece. So, D follows C.

If A were to follow D, we cannot place B in the paragraph. However, the sentence order BA does make sense after CD. So, the correct order is CDBA.

The question is " Arrange the sentences in the correct order "
The order is CDBA

Hence, the answer is CDBA
Choice D is the correct answer.

CRPF Head Constable Mock Test - 8 - Question 24

Directions: Read the following passage carefully and answer the questions given beside.

Remote sensing and GIS are promising tools for handling spatial and temporal data and help in integrating them for successful planning of natural resources. It is the science of measuring the earth using sensors mounted on high-flying aircrafts or satellites. These sensors collect data in the form of images and provide insights for manipulating, analysing and visualising those images. Since natural resources are not uniformly distributed and are spatially varied, it is challenging to capture the correct picture. Management of natural resources calls for scientific tools for timely and accurate dissemination of information. In natural resource management, remote sensing and GIS are mainly used in the mapping process. These techniques are useful in management of land, soil, coastal, watershed, urban and many more.

In India, the agriculture sector alone sustains the livelihood of around 50 percent of the population. Therefore, an increase in crop productivity has been a major concern. Since, the scope for increasing area under agriculture is limited, advanced crop production forecasting is required for better policymaking. Indian Space Research Agency (ISRO) and Indian Council of Agricultural Research (ICAR) successful experiment-Agricultural Resource Inventory and Survey Experiment (ARISE) used aerial colour photographs to estimate crop acreage in many states of India. Other Important uses of remote sensing include crop identification, stress detection, and crop yield modelling, drought monitoring, land degradation mapping and more. Urbanisation is important and inevitable for development, but its proper planning and management is crucial for sustenance. One of the important features of GIS is multilayered mapping. This kind of mapping helps municipal corporations, town planning boards to build cities that are better organised. The information systems with socio-economic data overlaid upon satellite data makes urban planning cost-effective and accurate. 

Coastal ecosystems have high ecological significance. GIS and remote sensing data are used to study coastal ecosystems and marine living resources which include habitats like mangroves, coral reefs and more. Apart from this, suspended shoreline dynamics can be studied and climatic changes leading to cyclones and sea level rise may be of special interest too. Geospatial data is effective in the analysis and determination of factors that affect the utilisation of these resources. The technologies provide a platform through which we can generate information that can be used to make sound decisions for sustainable development of the natural resources of India.

Q. How effective are remote sensing and GIS in managing urban growth?

I. GIS and remote sensing are helpful in building cities that are better organized.
II. The system makes urban planning cost-effective and accurate.
III. They help the government disseminate people living in extremely densed areas to less populated ones. 

Detailed Solution for CRPF Head Constable Mock Test - 8 - Question 24

From the highlighted  part in the sentence above, it’s clear that Statement II is  true. Hence, statement II is valid too. 
Statement III. They help the government disseminate people living in extremely densed areas to less populated ones. 
Nothing about the population is mentioned in the passage. Clearly, statement III is not true.

Option B is hence the correct answer.
