Key Points

• To answer this question, let's first understand the meaning of the highlighted word "amplify" in the context of the passage:
• Amplify - to make something larger, greater, or more intense; to increase the strength or amplitude of (बढ़ाना)
  • For Example:
  • The microphone was used to amplify the speaker's voice in the auditorium.
• Now, let's consider the options:
• Diminish - to make or become less; to reduce or decrease (कम करना)
  • For Example:
  • The medicine is expected to diminish the pain.
• Isolate - to set apart or separate from others; to be or remain alone (अलग करना)
  • For Example:
  • The scientist will isolate the specific gene responsible for the trait.
• Alleviate - to make a situation or symptom less severe or more bearable (कम करना)
  • For Example:
  • The relief efforts aim to alleviate the suffering of the affected population.
• Exacerbate - to make a situation, problem, or negative feeling worse or more severe (बढ़ाना)
  • For Example:
  • The economic downturn could exacerbate unemployment rates.
• Illuminate - to make something clearer or brighter; to light up (प्रकाशित करना)
  • For Example:
  • The streetlights will illuminate the dark alley.
• So, after understanding the meaning of the highlighted word "amplify" and all the words given as options, we can conclude that the word "exacerbate" is the most similar in meaning to the word "amplify" in the context of the passage, as both words involve making a situation more intense or severe.
• Therefore, the correct answer is "Exacerbate."

The correct answer is option 3.

Key Points

• To answer this question, let's first understand the meaning of the highlighted word "susceptible" in the context of the passage:
• Susceptible - likely or liable to be influenced or harmed by a particular thing (प्रभावित होने वाला)
  • For Example -
  • Children with weak immune systems are more susceptible to infections.
• Now, let's consider the options:
• Vulnerable - susceptible to physical or emotional harm or attack (असुरक्षित)
  • For Example -
  • The elderly are often vulnerable to scams targeting their financial resources.
• Permeable - allowing liquids or gases to pass through; full of holes (प्रवाही)
  • For Example -
  • The membrane is permeable to water molecules.
• Resistant - offering resistance to something; not easily affected or harmed by it (प्रतिरोधी)

Susceptible implies being likely to be influenced or harmed, while resistant indicates being not easily affected or harmed.
• Therefore, the correct answer is "Resistant."

The correct answer is option 4) i.e. B-E.

Key Points

Let us look at the sentence in the following way-

When, however, the human mind was (A) ________ by the torch-light of science, it came to understand that the Earth was but one of a (B) ________of stars (C) ________ in (D) ________space, a mere (E) ________ of dust.

• It is clear that A and C are correct and D justifies the bold word.
• We cannot use speck with stars as stars are not substances. Also, dust cannot be counted so we cannot use myriad. We need to interchange B and E to make the sentence correct.

Additional Information

Meanings of the words given in bold are:

• Illumined means light up; brighten.
• Myriad means a countless or extremely great number of people or things.
• Speck means a small particle of a substance.
• Floating means moving or hovering slowly and lightly in a liquid or the air; drift.
• Infinite means limitless or endless in space, extent, or size; impossible to measure or calculate.

Corrected sentence - 'When, however, the human mind was (A) illumined by the torch-light of science, it came to understand that the Earth was but one of a (B) myriad of stars (C) floating in (D) infinite space, a mere (E) speck of dust.' 

The correct answer is EDBCA.

Key Points

• To find the correct sequence of the words in the paragraph, we need to find the meanings of the given words first; Let's look at the given table:

• As the given table clarifies the meaning of the given words, we can infer the following points:
  • The first blank should be filled with the word rendered as the sentence is in the passive voice; hence past participle form of the verb should be followed by the helping verb is.
  • The second blank should be filled with the word away as wash away is a phrasal verb which means to be removed or carried away by a moving body of water, and it is used as it is.
  • The third blank should be filled with the word assists as the sentence is started with the singular subject Indian culture, and hence the singular verb assists should follow it.
  • The fourth blank should be filled with the word traditions as the blank is preceded by a pronoun these, which refers to a plural noun, and when we look at the rest of the words, the only word that fits here is traditions.
  • The fifth blank is left with the option worthy; also, the blank is preceded by a pronoun ourselves, which should follow an adjective worthy, as an adjective modifies a noun, here to make the sentence sensible.

Hence the complete paragraph is:
All our cleverness is rendered ineffective when nature does a dance of destruction. Its fury can and will wash away all imperfections. Indian culture, based on Vedic treatises, assists in human evolution, but we are using our entire energy in distorting these traditions according to our convenience instead of making efforts to make ourselves worthy of them

The correct answer is Option 3.

Key Points

• The original sentence is awkwardly phrased and does not clearly convey the meaning. The main issue is the placement and form of the words at the beginning of the sentence, making it hard to understand who is doing what.

• Option 3, "Claims against EU Member States," correctly reformulates the sentence to clearly indicate that the claims are directed against EU Member States by disappointed energy sector investors. This option corrects the grammatical structure and improves clarity.

• The original sentence's structure makes it difficult to immediately grasp the subject and object, which is clarified by the correct option.

Therefore, the correct answer is ‘Claims against EU Member States’.

Additional Information

• Option 1, "Claims against EU Members State," incorrectly uses "State" in the singular form where the plural is needed, as it is referring to multiple EU Member States.
• Option 2, "Claims against EU Members States," is grammatically incorrect due to the unnecessary plural form of "Members" when it should be "Member States" to correctly refer to the states as members of the EU.
• Option 4, "Claim against EU Member States," uses the singular "Claim" which is less accurate since the context suggests a trend of multiple claims rather than a singular instance.

Given:

Speed of a boat in still water = 15 kmph

Speed of the current = 9 kmph

Formula:

Speed downstream = Speed of a boat in still water + speed of a stream

Speed upstream = Speed of a boat in still water – the speed of a stream

Calculation:

Let distance traveled in downstream be A km.

Upstream distance travelled by boat = (A – 6)km

Speed downstream = 15 + 9 = 24 kmph

Speed upstream = 15 – 9 = 6 kmph

Then,

⇒ (A – 6)/6 – A/24 = 5

⇒ 24A – 144 – 6A = 720

⇒ A = 48km

Downstream distance = 48km

Upstream distance = 48 – 6 = 42 km

∴ Total distance travelled by boat = 48 + 42 = 90 km

Concept used:

Follow BODMAS rule to solve this question, as per the order given below.

Step - 1: Parts of an equation enclosed in 'Brackets' must be solved second, and following BODMAS rule in the bracket

Step - 2: Any mathematical 'Of' or 'Exponent' must be solved next.

Step - 3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated.

Step - 4: Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

Calculations:

5265 ÷ 117 + 67 × 85 - 1172 + 289 + 263 - 120 = (?)

⇒ 45 + 5695 - 1172 + 289 + 263 - 120 = (?)

⇒ 45 + 5695 - 1172 + 289 + 263 - 120 = (?)

⇒ 6292 - 1292 = (?)

⇒ ? = 5000

Hence, the correct answer is 5000.

Given:

(37.5% of 1615.86)/(100.97 × 0.995) = √?

Concept Used:

Follow the BODMAS rule according to the table given below:

Calculation:

Since we need to find out the approximate value, we can write these values to their nearest integers.

(37.5% of 1615.86)/(100.97 × 0.995) = √?

⇒ (37.5% of 1616)/(101 × 1) = √?

⇒ (3/8) × 1616/101 = √?

⇒ √? = 3 × 202/101

⇒ √? = 3 × 2

⇒ ? = 6²

⇒ 36

∴ The value of ‘?’ Is 36.

Given:

Distance covered in car = 18 km

Formula Used:

Distance = Speed x Time

Average speed = Total Distance/Total time

Calculation:

Let total distance = 10X

Journey on bike = 10X/ 4

Journey on bike = 2.5X

Remaining distance = 7.5X

Journey on car = (3 / 5) × 7.5X

Journey on car = 4.5X

⇒ 4.5X = 18

⇒ X = 4

Total distance = 40 km

Average speed = 40/ 4

Average speed = 10 kmph

∴ Average speed of journey is 10 kmph

Alternate Method

Distance covered in car = 18 km

Distance covered in taxi = 18/3 × 2 = 12 km

Let the total distance be 4x

Distance covered by car and taxi = 3x

⇒ 3x = 12 + 18

⇒ 3x = 30

⇒ 4x = 40

Average = 40/4 = 10 kmph

∴ Average speed of journey is 10 kmph

Given statements: E ≥ H < N ≤ D = Y, H > Q = R

On combining: E ≥ H > Q = R, R = Q < H < N ≤ D = Y

Conclusions:

I. Y > Q → True (as Q < H < N ≤ D = Y, so it is definite that Y is greater than Q.)

II. D > R → True (as R = Q < H < N ≤ D, so it is definite that D is greater than R.)

Both conclusions directly follow after combining the given statements.

Hence, the correct answer is Both I and II follow.

Left side 7 8 6 % = 2 $ T U V @ E 5 4 8 & M A K L 3 9 X Z O N ~ 0 B Right side

2^nd element from left side is 8 and 3^rd element from right side is ~ .

Left side 7 8 6 % = 2 $ T U V @ E 5 4 8 & M A K L 3 9 X Z O N ~ 0 B Right side .

Symbols are there in the above arrangement between the 2nd element from the left end and 3rd element from the right side: %, =, $, @, &

Hence, only five symbols are there in the above arrangement between the 2^nd element from the left end and the 3^rd element from the right end.

Left side 7 8 6 % = 2 $ T U V @ E 5 4 8 & M A K L 3 9 X Z O N ~ 0 B Right side

2^nd element from the right end is 0 and 3^rd element from the left side of 0 is O.

Hence, O is the 3rd element to the left of the 2nd element from the right end.

Hence, D is the nephew of I.

The correct answer is "option 1.

CONCEPT:

An idea behind templates is to pass any data type as a parameter to the function so that the need for writing the same code for different datatypes decreases.

Templates are mechanisms used to implement the generic concepts.

Generics allows datatype as a parameter to classes, functions & interfaces.

EXPLANATION:

Templates are of two types: Class templates & Functions templates

Function templates are used to write generic functions that can be used for different data types.

Class templates are the classes that have members of generic type.

Class templates & function templates are instantiated in the same way.

But class templates are not used for storage classes & are not initiated by defining an object using the template argument.

Hence, the correct answer is option 1

Answer: Option 1)

Concept:-

Meaning of i++: [post increment]

First, we read i then after reading the value of i we are going to increment i this is nothing but post-increment.

Meaning of ++i: [pre increment]

First we increment i than we read value of I, this is nothing but pre increment:

Explanation:

b=1;

c=5;

this will assign value 1,5 to variables b and c respectively

a=0-(++b)+c++;

In this expression first, b will be pre incremented.

a = 0 -(2) + c++;

and then c's value will be returned after that c will be incremented because of post-increment.

a = 0 - (2) + 5; // c will become 6

Hence a = 3, b = 2, c= 6

The correct answer is option 4.

• A computer virus is a type of malicious software that, when executed, replicates itself by modifying other computer programs and inserting its own code.
• When this replication succeeds, the affected areas are then said to be "infected" with a computer virus
• Examples: computer "worms", ransomware, spyware, adware, keyloggers, rootkits, bootkits etc.
• Spyware
  • It is unwanted software that infiltrates your computing device, stealing your internet usage data and sensitive information.
  • Spyware is classified as a type of malware — malicious software designed to gain access to or damage your computer, often without your knowledge. Spyware gathers your personal information and relays it to advertisers, data firms, or external users.
• Keylogger
  • A keylogger is a program that records the keystrokes on a computer. It does this by monitoring a user's input and keeping a log of all keys that are pressed. The log may be saved to a file or even sent to another machine over a network or the Internet.
  • Keylogger programs are often deemed spyware because they usually run without the user knowing it. They can be maliciously installed by hackers to spy on what a user is typing.
• Ransomeware
  • A type of malicious software designed to block access to a computer system until a sum of money is paid.
  • It has the ability to lock a computer screen or encrypt important, predetermined files with a password.
• Trojan horses
  • A Trojan horse is not a virus because it avoids replicating itself.
  • A Trojan horse, or Trojan, is a type of malicious code or software that looks legitimate but can take control of your computer.
  • A Trojan is designed to damage, disrupt, steal, or in general inflict some other harmful action on your data or network.

Key Points
Adelson-Velskii and Landis (AVL) tree is a height-balanced binary search tree. An AVL tree is a balanced binary search tree. In an AVL tree, the balance factor of every node is either -1, 0, or +1. The balance factor of a node is the difference between the heights of the left and right subtrees of that node.

So at every node of the AVL tree must satisfy the |h(TL) - h(TR)| ≤ 1.

Hence the correct answer is |h(TL) - h(TR)| ≤ 1.

Additional Information

• In an AVL tree, a single insertion may cause at most 2 rotations in the worst case.
• In an AVL tree, a single deletion may cause multiple rotations in the worst case.

The correct answer is option 2.

Concept:

Bash, or the Bourne-Again Shell, is by far the most widely used choice and it comes installed as the default shell in the most popular Linux distributions. It was derived from the original UNIX Bourne shell (also known as sh) and was created to be fully compatible with previous scripts while also incorporating numerous improvements.

Bash is a fairly reliable shell choice because it has been around for a long time and has a lot of documentation. In fact, most online tutorials presume you're familiar with bash.

As a result, it is recommended for the majority of users and performs admirably for the majority of common system administration chores. If you require more sophisticated scripting options or other advanced tools, however, you should look into some of the newer shells.

Hence the correct answer is bash Shell.

User Datagram Protocol (UDP):

• UDP is an unreliable connectionless-transport layer Protocol used for its simplicity and efficiency in applications where error can be provided by the application layer
• UDP provided process-to-process communication

The correct answer is dropna()

Key Points

• The .dropna() method in pandas is used to remove missing values (NA/NaN values) from the dataset. When used without any parameters, dropna() will remove any row in the DataFrame that contains at least one missing value.
• Here is a basic example:

import pandas as pd
import numpy as np

# Creating a DataFrame with some NaN values
df = pd.DataFrame({'A': [1, 2, np.nan], 'B': [5, np.nan, np.nan], 'C': [1, 2, 3]})

print("Before dropping NaN values: ")
print(df)

print("\nAfter dropping NaN values: ")
print(df.dropna())

• In the output, you will see that any row which had a NaN value will be removed.
• You also have the option to drop columns that contain missing values by using df.dropna(axis=1). This drops any column with a NaN value.
• Furthermore, you have other ways of handling missing data, such as the fillna() function, which allows you to fill NaNs with any value you choose, rather than removing them.

The correct answer is option 1.

Concept:

$@ treats each quoted argument as separate arguments. $@ which means, ‘All of the command-line arguments to the shell script’. We also should put $@ inside double quotes to handle the case of arguments containing spaces ("$@" is special syntax and is equivalent to "$1" "$2" …).

Example 1:

for var in "$@"

do

echo "$var"

done

input 1: 1 2 "3 4"

output:

1

2

3 4

input 2: " 1 2 3 4"

output:

1 2 3 4

$* considers the entire set of positional parameters as a single string. $* is all the parameters to the script or function, split into separate arguments on whitespace.

Example 1:

for var in $*

do

echo "$var"

done

input 1: 1 2 "3 4"

output:

1

2

3

4

input 2: " 1 2 3 4"

output:

1

2

3

4

Hence the correct answer is $@ treats each quoted argument as separate arguments but $* considers the entire set of positional parameters as a single string.

The correct answer is option 3.

Concept:

The seek() method :

This method is used to position the file object at a particular position in a file.

The syntax of seek() is:

file_object.seek(offset [ , reference_point])

In the above syntax, offset is the number of bytes by which the file object is to be moved. reference_point indicates the starting position of the file object. That is, with reference to which position, the offset has to be counted.

• It can have any of the following values:
  • 0 - beginning of the file
  • 1 - current position of the file
  • 2 - end of file
• By default, the value of reference_point is 0, i.e. the offset is counted from the beginning of the file.

Hence the correct answer is seek().

Additional Information The tell() method:

This function returns an integer that specifies the current position of the file object in the file. The position so specified is the byte position from the beginning of the file till the current position of the file object.

The syntax of using tell() is:

file_object.tell()

The correct option is Syntax Error

CONCEPT:

Syntax errors occur when the programmer does not follow or makes mistake in the syntax of a particular programming language

Common syntax errors in python:

• leaving out a keyword.
• misspelling a keyword.
• leaving out a symbol, such as a comma, brackets....etc.

In Python, assignment using `=` operator is not allowed inside an condition of if statement

The error thrown will be "SyntaxError: invalid syntax. Maybe you meant '==' or ':=' instead of '=' ".

Syntax of if statement in python:

if condition:

# code to execute in case if the above condition is true

Additional Information

IOError is raised when an input/output operation fails.

The correct answer is option 3.

Concept:

The Simple Mail Transfer Protocol (SMTP) is a communication protocol used on the internet for electronic mail transmission. SMTP is used by mail servers and other message transfer agents to send and receive email messages. User-level email clients typically use SMTP only for relaying messages to a mail server and submitting an outgoing email to the mail server.

• SMTP servers typically use the Transmission Control Protocol on ports 25 (for plaintext) and 587 (for encrypted data) (for encrypted communications).
• SMTP is important because it establishes a standard set of guidelines for transferring messages from one email host to another. Essentially, SMTP is the only way to send an email from one provider to another without losing any content or functionality.

Hence the correct answer is 25.

Additional Information

• SMTP makes use of Port 25.
• It makes use of persistent TCP connections and thus can send multiple emails all at once.
• It is a stateless protocol.
• It is a connection-oriented protocol.
• It makes use of TCP at the transport layer.
• It is a push control protocol.

Correct answer is Option C
Key Points
Following will be contents of temporary table S

Following will be contents of temporary table T

• Following will be the result of natural join of above two tables.
• The key thing to note is that the natural join happens on column name with same name which is Manager in the above example.
• “Hari” appears two times in Manager column, so there will be four entries with Manager as “Hari”.

The correct answer is Attack Surface.

Key Points

• The attack surface:
  • It is the number of all possible points, or attack vectors, where an unauthorized user can access a system and extract data.
  • The smaller the attack surface, the easier it is to protect.
  • Organizations must constantly monitor their attack surface to identify and block potential threats as quickly as possible.
  • They also must try and minimize the attack surface area to reduce the risk of cyberattacks succeeding.
  • However, doing so becomes difficult as they expand their digital footprint and embrace new technologies.

  • The attack surface is split into two categories: the digital and physical.
