Train delays have always been a problem for people of developed as wel

Question

Train delays have always been a problem for people of developed as well as developing countries. Even after all the progress we have made, we have not been able to solve this problem. According to Plamen Angelov, a researcher from the University of Lancaster, train delays are caused not by the operators but by the passengers. For instance, in order to board a train, passengers block its door, restricting the deboarding passengers and delaying the departure of the train. Some of them hold the doors open or stay too close to the door while some cross the safety lines on the platform, delaying the trains every time. A delay of a few minutes may not appear to be signi}cant until these minutes add up over the course of a journey. Dr Angelov plans to solve this problem with the help of an Artificial Intelligence (AI) system. He and his team plan to use images from the CCTV cameras already present in the train carriages to calculate how busy a particular exit will get as passengers prepare to disembark. At the same time, the cameras present on the platform will observe the number of people waiting to board the train. Both the data points will then be fed to the AI system that can analyze the data to find out the likely areas of congestion, and accordingly, can route the passengers so that the overall congestion can be reduced to a signi}cant extent. If this system turns out to be successful, AI will win the credit for solving one of the oldest problems faced by the modern society.     1

3. Which of the following is not true as per the passage?

Difficulty Level:   550

Explanation

Main Point:  Describe a study being carried out to use AI for reducing train delays.

(A)  Out of Scope: Can be inferred. … Both the data points will then be fed to the AI system that can analyze the data…

(B)  Out of Scope: Can be inferred. The passage discusses the observations and plans of PA who states the passenger behavior is the main reason for train delays and suggests a plan to control passenger behavior to avoid train delays.

(C)  The passage does not discuss the cost aspect of the AI system being planned. Hence, this choice cannot be inferred.

(D)  Out of Scope: It has been mentioned in the passage. Even after all the progress we have made, we have not been able to solve this problem.

(E)  Out of Scope: It has been mentioned in the passage. …the AI system that can analyze the data to find out the likely areas of congestion, and accordingly, can route the passengers so that the overall congestion can be reduced to a significant extent.

Answer: C

Chanthu · Answer

the answer to the question 3 is c ,because all the except c are disscussed in the passage.

Hi All,

Please explain the answer for question no 2.

As per my understanding it is no where mentioned that "Dr Angelov" states "Passenger behavior" as a reason for the delay, it was as per author.

Check the 4th line as it says 
“ According to Plamen Angelov, a researcher from the University of Lancaster, train delays are caused not by the operators but by the passengers.”

This is stated in the passage, so the correct answer is D

Explanation

1. What is the main point of the passage?

Difficulty Level:   500

Explanation

A.  This option is not the main point of the passage. While the passage discusses a problem (train delays) that affects both developed and developing countries, it does not aim to discuss all the problems faced by these countries. The primary focus is on one specific problem (train delays) and a proposed solution using AI.

B.  The passage does mention Dr. Angelov's plan to use AI to address train delays, but the primary purpose of the passage is not to evaluate this plan. Instead, it presents the plan as a potential solution to a long-standing problem without going into detailed evaluation or analysis.

C.  This option is not the main point of the passage either. While the passage mentions the cause of train delays (passenger behavior) and suggests a technological solution, it does not delve into a detailed description of why the problem could not be solved in the past.

D.  The passage does briefly describe passenger behavior as a contributing factor to train delays, but it does not primarily focus on discussing passenger behavior. The main point of the passage is to introduce the problem of train delays and propose a technological solution using AI.

E.  This is the correct answer. The passage's main point is to introduce the problem of train delays (a long-standing problem) and explain a plan proposed by Dr. Angelov to address this problem using AI technology. The passage outlines the problem and the potential solution, making this the central theme of the passage.

In summary, option E accurately captures the main point of the passage by emphasizing the description of a long-standing problem (train delays) and the proposed technological solution to address that problem.
