The logic that follows here is 

1) D is sitting to the immediate left of A.

2) C is sitting to the immediate right of B.

3) B is not sitting adjacent to A.

The final seating arrangement will be

Second to the right of D is 'E'.

Hence, the correct answer is E.

Given statements: K > M < L = Z = O < P.

Conclusions:

I. P < Z → False (As, L = Z = O < P → P > Z).

II. M = Z → False ( M < L = Z → M < Z and L = Z).

Hence, "Neither Conclusion I nor II correct".

Logic: The alphabet that comes first alphabetically, comes first in the dictionary.

So, the correct arrangement should be:

2. Subtle.

4. Sucres.

3. Sudoku.

1. Sugary.

5. Sullen.

Hence, the correct answer is "2, 4, 3, 1, 5".

As Cloth is made in a Mill, similarly Newspaper is printed in press.

Given figure are -

From option 1 - Doctor, Man, Student

Some doctor are man, some man are student, some doctor are student.

So It is the best representation of the venn diagram.

Let A  = Doctor, B = Man, C = Student

From option 2 - table, Chair, Furniture

No table is chair, some furniture are table as well as chair. It is not correct representation of the venn diagram.

From option 3 - Gold, silver, ornaments

It is not correct representation of the venn diagram.

From option 4 - Family, Parents, Children

 It is not correct representation of the venn diagram.

Hence, "option 1" is the correct answer.

- In this analogy, an ornithologist studies birds, so we need to find a similar relationship for an archaeologist. An archaeologist is a specialist who studies human history through excavation and analysis of artifacts.

• An ornithologist focuses on a specific animal group: birds.
• Similarly, an archaeologist focuses on remnants of past human activities, which are primarily artifacts.
• Other options like islands, mediators, and aquatic do not relate directly to the field of archaeology.

Thus, the appropriate term to complete the analogy is artifacts.

Dynasty : a series of rulers of a country who all belong to the same family
Lineage : the series of families that somebody comes from originally
Ancestry : the family or the race of people that you come from
Progeny : a person's children ; The young of animals and plants

The word Grotesque (Adjective) means: strange in a way that is unpleasant: extremely ugly, unusual
Hence, the words grotesque and natural are antonyms. 

• Identifying the missing word: We need to find the word that fits best in blank number 14 based on the context provided.


• Understanding the context: The sentence talks about ancestors punishing individuals who failed in their duty, indicating that those individuals were chastised by the ancestors.


• Analysis: The word "who" is the most appropriate choice for blank number 14 as it refers to individuals (people) who failed in their duty.


• Conclusion: Therefore, the correct answer is option A: who.

• Identifying the Context: The sentence mentions an explanation that is heard in a certain situation.


• Understanding the Tone: The tone of the sentence suggests a pattern or frequency of occurrence.


• Considering the Options: Review the options provided to determine which one best fits the context and tone.

• Choice D: often - This word implies a frequent or regular recurrence, which aligns with the explanation being commonly heard in the context provided.

Repeal: To revoke or annul a law, regulation, or decision, typically through official or legislative means.

1. Sanction:

   • As a verb: to give official permission or approval for an action.
   • As a noun: a penalty or measure taken against someone who has violated a rule or law.

2. Perpetuate: To make something continue indefinitely; to sustain or prolong.

3. Pass:

   • As a verb: to approve or adopt a proposal or legislation.
   • As a noun: a successful attempt to achieve something; also, a document or ticket granting authorization or access.

4. Cancel: To revoke or annul something previously scheduled, arranged, or agreed upon; to declare null and void.

Correct option D

One word substitution is Centrifugal.

Centrifugal: moving or tending to move away from a centre.
Centripetal: moving or tending to move towards a centre.
Axiomatic: self-evident or unquestionable.
Awry: away from the usual or expected course
 

The segment is in passive voice, thus only a verb in third form is eligible for the blank. Among all the given options, only ‘discovered’ fits the blank as the virus already existed in the monkeys but was found in 1970.

Hence, option D is correct.

Routing in OSI Network Architecture

Answer: B. Data link layer

Explanation:

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven different layers. The routing process, which involves the selection of the best path for data packets to travel from the source to the destination, is primarily performed by the network layer in the OSI model. However, the data link layer also plays a role in routing by facilitating the transmission of data between directly connected nodes or devices. Here's a breakdown of the routing process in the OSI model:

1. Network Layer:

• The network layer is responsible for logical addressing, routing, and path determination.


• It receives data from the transport layer and adds network layer headers to create packets.


• It determines the best path for packet transmission based on the destination address and network conditions.


• It uses routing protocols (such as OSPF, RIP, BGP) to exchange routing information and build routing tables.


• It forwards packets to the next hop or the next network based on the routing table.

2. Data Link Layer:

• The data link layer provides reliable point-to-point communication between directly connected nodes.


• It encapsulates the network layer packets into data frames and adds data link layer headers and trailers.


• It performs error detection and correction using techniques like CRC (Cyclic Redundancy Check).


• It controls the flow of data between devices to avoid congestion.


• It uses MAC (Media Access Control) addresses to identify devices on the same network.


• It performs local network routing by forwarding data frames to the appropriate device based on MAC addresses.

While the primary responsibility of routing lies with the network layer, the data link layer contributes to the routing process by facilitating communication between directly connected devices. Therefore, in the OSI network architecture, routing is performed by both the network layer and the data link layer.
