whihch one is better pick 1. The aim of this research investigation is to determine the impact of vaccination coverage on the number of measles cases and the spread of diseases controlled by the Australian government’s MMR vaccination program on the incidence rate. To strengthen the validity of this report, the solution to the research question has been reached based on a systematic review of research journals and websites. Based upon the analysis and interpretation of three relevant pieces of evidence of vaccine coverage rate with number of measles cases and herd immunity of vaccines, has been found that the increase in MMR vaccine coverage has a statistically significant effect on the decreasing incidence rate of measles infection. or The purpose of this research is to examine how vaccination coverage impacts the number of measles cases and the spread of diseases controlled by the Australian government's MMR vaccination program. To ensure the credibility of this report, a systematic review of research journals and websites was conducted to find a solution to the research question. After analyzing and interpreting three pieces of evidence related to vaccine coverage rate, number of measles cases, and herd immunity, it was discovered that an increase in MMR vaccine coverage has a significant effect on reducing the incidence rate of measles infection.

Both statements convey the same objective and findings of the research investigation. The choice between the two is subjective and depends on personal preference or the required writing style for the specific context or audience.

Both statements convey similar information, but there are some minor differences in wording. Here is a breakdown of each statement:

Statement 1:
1. The aim of the research investigation is to determine the impact of vaccination coverage on the number of measles cases and the spread of diseases controlled by the Australian government's MMR vaccination program on the incidence rate.
2. The validity of the report has been strengthened by conducting a systematic review of research journals and websites.
3. The analysis and interpretation of three relevant pieces of evidence, which include vaccine coverage rate, number of measles cases, and herd immunity, demonstrate that an increase in MMR vaccine coverage significantly decreases the incidence rate of measles infection.

Statement 2:
1. The purpose of the research is to examine how vaccination coverage impacts the number of measles cases and the spread of diseases controlled by the Australian government's MMR vaccination program.
2. To ensure the credibility of the report, a systematic review of research journals and websites was conducted.
3. After analyzing and interpreting three pieces of evidence related to vaccine coverage rate, number of measles cases, and herd immunity, it was discovered that an increase in MMR vaccine coverage significantly reduces the incidence rate of measles infection.

In terms of which one is better, it depends on personal preference and context. Both statements provide clear objectives, explain the methodology used, and present the findings. You could choose the statement that aligns better with your writing style or the specific requirements of your research report.
