From this source, I can infer that teenagers had a stable education because they it was compulsory for them to attend school. I can also infer that school life was hard and stressful because they were forced to learn Japanese. This could be seen when "existing schools were pressured to teach their curriculum in Japanese" which tells us that the schools were reluctant to change the main language of English to Japanese to teach their students. In order for students to learn Japanese more efficiently, "lessons were played over the schools’ broadcasting systems. This shows that Japanese was drilled into the students' brain every time. Hence, with these factors, I can conclude that students had a stable education.

Before
SOURCE B

Source: http://www.nas.gov.sg/archivesonline/article/memories-of-joshua-benjamin-jeyaretnam; Joshua Benjamin Jeyaretnam as interviewee, interviewed from 2005 through August 2008. 

From this source, I can infer that education was not as stressful as the education received during the Japanese occupation. This could be seen from "there wasn't that pressure on us and the teaching was good." This shows that students were not forced to learn anything they didn't like. 

From these two sources, I can infer that there is no difference between the school life of teenagers, as they still attended school before and during the Japanese occupation. However, there is a change of content in what the students learnt. Before the Japanese occupation, students learnt their mother tongue, however, during the Japanese occupation, students were forced to take up Japanese as a subject, which was very hard to understand.

SOURCE A

This source tells me that the people had enough food and proper clothing from the quote "Food, imported or native-grown,tinned,frozen or fresh, was plentiful and so was clothing. This means that the people had sufficient food and clothing. I can infer that there were no shortage of food during that time. Thus, teenagers had plenty of food to eat before the Japanese occupation

During
SOURCE B

This picture shows a family with a family with a father and a girl eating porridge together in a mess up house with dirty clothes. This shows how horrible their life was to survive in that harsh condition.

From the first source, the people said that they had enough food and clothing while the people in the second source shows that their food and clothing were horrible. This means before the Japanese Occupation and during the Japanese Occupation has a difference in the lifestyle of people. I can infer that teenagers during the Japanese occupation did not have a lot of food to eat due to food shortage or the food that they only have left to eat is porridge. Thus, There was a big difference in the food teenagers ate during and before the Japanese occupation.
