Question 1

The following sentence has been divided into parts. One of them contains an error.
Select the part that contains the error from the given options.
Four of earliest civilisations / of the world / were located / on the banks of or near large
rivers.

Accepted Answer

The error is in part 3. When using 'of the' before a superlative adjective (earliest), a definite article 'the' is required before the superlative. So, it should be 'Four of the earliest civilisations'.

Question 2

Select the most appropriate ANTONYM of the given word.
Conceited

Accepted Answer

The word 'conceited' means excessively proud of oneself; arrogant. The most appropriate antonym is 'modest', which means humble or unpretentious. Options like 'superior', 'proud', and 'vain' are synonyms or closely related in meaning to 'conceited'.

The idiom 'Lion's share' refers to the largest or best part of something. Option 3 accurately captures this meaning.

Question 4

A live wire

The idiom 'a live wire' refers to someone who is full of energy and very active. Option 3 accurately describes this meaning.

Question 5

The following sentence has been divided into parts. One of them contains an error. Select
the part that contains the error from the given options.
The food / in the new eatery / is much best than / the one in RK Puram.

Accepted Answer

The error lies in the use of 'much best'. When comparing two things, the comparative degree should be used. The correct comparative form of 'good' is 'better', making the phrase 'much better than'.

Question 6

Through which of the following actions does the lithosphere move over the asthenosphere?

Accepted Answer

The movement of the lithosphere over the asthenosphere is primarily explained by the theory of plate tectonics. Continental drift is a historical concept that described the movement of continents, which is now understood as a consequence of plate tectonics.

Question 7

Select the INCORRECTLY spelt word.

Accepted Answer

The question asks to identify the incorrectly spelt word. 'Licenced' is correctly spelt as 'Licensed' in British English or 'Licensed' in American English. 'Aesthetic', 'Haphazard', and 'Chandelier' are all correctly spelt.

Question 8

Select the most appropriate option to ﬁll in the blank.
His ______ of the topic was so good that students had few doubts at the end of the class.

Accepted Answer

The sentence implies a clear and detailed explanation of a topic. 'Exposition' means a comprehensive description or explanation of an idea or theory, which fits perfectly. 'Picturisation' refers to forming a mental image, which is less direct for explaining a topic in a classroom setting.

Question 9

Select the option that expresses the given sentence in passive voice.
Richard wore a broad belt with shiny buckles.

Accepted Answer

To change an active voice sentence to passive voice, the object of the active sentence becomes the subject of the passive sentence, the verb is changed to 'be' + past participle form, and the original subject becomes the object of a 'by' phrase. The original sentence is in Simple Past Tense, so the passive form uses 'was/were' + past participle. 'Wore' becomes 'was worn'.

Question 10

Select the most appropriate option to ﬁll in the blank.
The lack of regular academic sessions has meant that in 2020 the country has had the
______ share of students who have attended educational institutions.

Accepted Answer

The sentence compares the share of students in 2020 to an implied general or previous state, indicating a comparative degree. 'Lowest' would require a comparison among three or more entities, and 'last' refers to order. 'Low' is the correct adjective to describe the share.

Question 11

Read the given statements and conclusions carefully. Assuming that the information given
in the statements is true, even if it appears to be at variance with commonly known facts,
decide which of the given conclusions logically follow(s) from the statements.
Statements:
All teachers are doctors.
Some professors are doctors.
All professors are engineers.
Conclusions:
I. All professors are doctors.
II. Some doctors are engineers.
III. Some teachers are engineers.
IV. Some teachers are professors.

Accepted Answer

Using Venn diagrams or logical deduction: 'All teachers are doctors' and 'Some professors are doctors' and 'All professors are engineers'. From 'All professors are engineers' and 'Some professors are doctors', we can deduce 'Some doctors are engineers'. No other conclusion necessarily follows.

Question 12

One of the major events of Ashoka’s reign was the convening of the ______ Buddhist Sangha
(council) in 250 BCE in the capital Pataliputra.

Accepted Answer

The Third Buddhist Council was convened in 250 BCE at Pataliputra under the patronage of Emperor Ashoka. This event is a significant part of Ashoka's reign and Buddhist history.

Question 13

The following sentence has been divided into parts. One of them contains an error. Select
the part that contains the error from the given options.
The army / marched fearless / towards / the enemy cantonment.

Accepted Answer

The word 'fearless' is an adjective, but an adverb is needed to modify the verb 'marched'. The correct word should be 'fearlessly'.

Question 14

Select the number from among the given options that can replace the question mark (?) in
the following series.
11, 13, 19, 49, 109, 239, ?

Accepted Answer

The pattern involves adding increasing multiples of 2, specifically 2^2, 2^3, 2^4, and so on, to the previous number. The differences are +2, +6, +30, +60, +130. This can be re-expressed as adding (n^3 - n) for n=2,3,4... or by observing the differences between terms: 13-11=2, 19-13=6, 49-19=30, 109-49=60, 239-109=130. The pattern for these differences is 2, 6, 30, 60, 130. This is not immediately obvious. Let's re-examine. The differences are: +2, +6, +30, +60, +130. This is not a simple arithmetic or geometric progression. Let's try another approach. The pattern is: 11 + (1^3 + 1) = 13, 13 + (2^3 - 2) = 19, 19 + (3^3 + 3) = 49, 49 + (4^3 - 4) = 109, 109 + (5^3 + 5) = 239. So the next term will be 239 + (6^3 - 6) = 239 + (216 - 6) = 239 + 210 = 449.

Question 15

In medicine, ______ is a device such as a small metal plate or needle that carries electricity
from an instrument to a patient for treatment or surgery.

Accepted Answer

The definition provided perfectly describes an electrode, which is used to conduct electricity to or from a patient. A machmeter measures speed relative to the speed of sound, an electrolyte is a substance that conducts electricity when dissolved, and a venturimeter measures fluid flow.

Question 18

Question 19

Select the combination of letters that when sequentially placed in the blanks of the given
series will complete the series.
G_CT_GP_T_GPC_D_PC_D

Accepted Answer

The given series is G_CT_GP_T_GPC_D_PC_D. By observing the pattern, we can identify a repeating block 'GPCTD'. Filling the blanks with the letters from option 1 (P, D, C, D, T, G, T) completes the series as GPCTDGPCTDGPCTD.

Question 20

Read the given information carefully and answer the question that follows.
‘K $ D’ means ‘K is the father of D’. 
‘K  D’ means ‘K is the daughter of D’.
‘K @ D’ means ‘K is the son of D’. 
How is S related to N in the expression ‘H > R $ S@T > N’?

Accepted Answer

Let's decode the expression: 'H > R' means 'H is the daughter of R'. 'R $ S' means 'R is the father of S'. 'S @ T' means 'S is the son of T'. 'T > N' means 'T is the daughter of N'. From these, we deduce the relationships: H is R's daughter. R is S's father. S is T's son. T is N's daughter. Combining these, R and T are parents of S. T is N's daughter, so N is T's parent (mother or father). Therefore, S is the grandson of N.
