Model Answer 1:
The given line graph shows data on the number of underground station passengers of London city from 6:00 am till 10:00 pm. As is observed from the graph, the highest number of people use the underground stations of London at 8:00 am and 6:00 pm.

At 6:00 am around 100 underground passengers can be found at the stations and this number increases seamlessly until 8:00 am when the passengers' number reaches to 400. After 8:00 am the number declines steadily until 10:00 am when it reaches at around 180. The number keeps fluctuating until 4:00 pm and on an average 200 passengers can be observed during this period. After 4:00 pm the passenger number increases and reaches at 380 at around 6:00 pm. After 6:00 pm, the passenger number decreases with some fluctuations until 10:00 pm.

In summary, the highest number of passengers of London underground stations can be found in the stations during the office going and office leaving times in a day.

Model Answer 2:
The graph shows the number of passengers travelling at various times in an underground station in London. As per the chart, there are 400 passengers travelling at 8.00 am and this seems to be the time that majority of the travelling takes place. This might be because people usually go to work or children to school at this time; hence, 8.00 am has the highest number of people using the underground station.

Moreover, the second highest numbers of travellers were, with a slightly less number than 8.00 am is the evening travel, at 18.00 having 390 travellers. Hence, the immediate justification would be as it is the time, people travelling back after work. However, it is noticeable that the least number of people use the underground at 4.00 pm and 6.00 am assuming it is the same type of people travelling back and forth at different times for starting work and finishing work. It is also observed that the number of people travelling (300) seems to happen frequently at different times during the day.

Overall, the time of the day that shows a high number of people using the underground station in London are at 8.00am and 6.00pm.

Sample Answer 3:
The provided line graph shows information about the numbers of people who use the underground station in London around the clock of a typical day. As is observed from the graph, the busiest times at underground station are 8:00 am and 6:00 pm.

The highest numbers of people use the station in the morning and more specifically at around 8:00 in the morning. A rapid growth can be observed between 6:00 am and 8:00 am in the morning when around 400 people use the station at around 7:30 am. This number then quickly drops to below 200 at around 10:00 am. Again this number rises between 11:00 and 3:00 pm when around 300 people use the underground station with some fluctuations.

In the afternoon, this number decline, with less than 100 people using the station at 4:00 pm. At 6:00 pm this number reaches at 380. After 7:00 pm, the total number of passengers declines significantly and fluctuates for last two hours from 8:00 pm to 10:00 pm.

In summary, London underground station remains busy in the starting of the day at morning and in the early evening.

Sample Answer 4:
The line graph depicts the variation in the number of London subway passengers during 6 a.m. to 22 p.m. on a typical day.

At a glance, busiest time is 8 a.m. and 6 p.m. To commence with, a large proportion of total people use underground railway facility at 8 a.m. and 6 p.m. which are about 400. From 6 a.m. to 8 a.m. the steep incline in the number of passengers from 100 to 400. In the next hour, it again plummets back into 175. Though there is a slight increase in the number of passengers, it remains same that is almost 300 from 12.00 to 2.00 p.m. Then the total figure of travellers declines 100 from 300 within two hours. Interestingly, at morning (6 a.m.) and at 4 p.m. almost an equal number of people use underground transportations, which is 100. In spite of a small hike at 9 p.m., the underground system has an equal number of travellers at 20.00 and 22.00 hours.

To conclude, London underground station remains busy at office hours.

Sample Answer 5:
The provided graph depicts the number of people who use the London Underground station from 6:00 am to 10:00 pm on a typical day. It can be seen that the usage of the station varies at different periods of the day but mostly it remains busy at 8.00 am and at 6.00 pm.

At 6:00 am, the number of passengers at the station is very low with a total of 90 passengers. However, it firmly increases up 200 to 7:00 am at which point the traffic witnesses a drastic plunge reaching the busiest point of the day with 400 passengers. In a subsequent couple of hours, the rush relieves a little to reach 180 passengers at 10:00 am. The following two hours observe a humble rise which eventually reached at 280 when it, thereafter, creep to 300 from 12:00 to 14:00. From this moment, passenger arrival faces a major decline to the daily low point of less than 100 occurring at 16:00 while it plunges again to the second maximum of 380 at 18:00. For 18:00 to 20:00, traffic eases a little bit to around 130 and finally the remain hours encountering little fluctuation at 150.
