Which country successfully launched the high throughput communication satellite Shijian 13 to provide high speed internet access?

Introduction / Context:
This question concerns space technology and communication satellites. Shijian 13 is a high throughput communication satellite developed to provide high speed internet and advanced communication capabilities. The question asks which country launched this satellite successfully.

Given Data / Assumptions:

• The satellite is named Shijian 13.
• It is a communication satellite with high throughput capability.
• The aim is to deliver high speed internet connectivity and related services.
• The options list several Asian countries with active space programmes.

Concept / Approach:
The name Shijian is associated with a series of experimental satellites developed by China. Shijian 13 in particular was a Chinese communication satellite launched to test high throughput internet services and advanced propulsion. Therefore, the correct approach is to associate the Shijian prefix with China s space programme and select China as the answer.

Step-by-Step Solution:
Step 1: Recognise that Shijian is a Chinese term and that satellites with this naming convention belong to the Chinese space programme. Step 2: Recall that China has launched several Shijian series satellites for experimentation and communication, including Shijian 13. Step 3: Note that the satellite was described in news reports as a high throughput communication satellite providing broadband services. Step 4: Match this knowledge with the options and select China.

Verification / Alternative check:
Space news archives and official Chinese announcements confirm that China launched Shijian 13 as part of its efforts to boost satellite based internet and communication infrastructure. The launch was carried out on a Long March rocket from a Chinese launch site. There is no evidence of Japan, Singapore, Indonesia or South Korea launching a satellite by this exact name.

Why Other Options Are Wrong:
Japan: Japan has its own series of satellites but not one named Shijian 13. Singapore: Singapore has a small space programme and did not develop this satellite. Indonesia: While active in satellite communications, Indonesia did not launch Shijian 13. South Korea: South Korea has launched its own satellites but not under the Shijian designation.

Common Pitfalls:
When unfamiliar with Chinese terminology, some examinees may guess a different Asian country at random. Others may mistakenly associate all high throughput satellites with countries like Japan due to advanced technology. Remembering that Shijian is a name tied specifically to Chinese experimental satellites avoids these errors.

Final Answer:
The high throughput communication satellite Shijian 13 was successfully launched by China.
