Lorenzo is conducting a research study to understand the correlation between the incidence of breast cancer and the age among women. The women in the research study are from the same ethnic background and belong to the upper middle class. Lorenzo selects 30 women for the study and then divides them into three groups based on their age. The first group consists of women aged 25-35, the second group consists of women aged 36-50, and the third group consists of women aged 51-65. Which of the following is likely to be a limitation in Lorenzo's method of research? a. It is likely to require taking multiple observations. b. It is likely to be time-consuming. c. The results are likely to reflect cohort differences. d. The participants are likely to drop out of the research.

The limitation of the research includes the fact that only one female out of 1500 which are of age group 25-35 have breast cancer. As age increases, the cases for breast cancer increase.

So, if Lorenzo uses this method of age bracket to understand correlation between the age and incidence of breast cancer, it would be time consuming as he needs to research for each group separately and then conclude.

Option D is incorrect as it says that participants would drop out. Option C about cohort difference is also incorrect as cohort differences research means people who born are of same age group share common experience but in this case research is being done on different age groups.

Lumps and cancerous cells form in the breast tissues and mammary glands are called breast cancer. Breast cancer generally affects women and rarely occurs in men.

In Lorenzo's method of research following is likely to be a limitation:

Option B: It is likely to be time-consuming.

This can be explained as:

The risk of getting cancer raises with the age and in the above data, only 1 in 1500 women in the age group of 25-30 have breast cancer.

As the age group of women increases, the data shows more women getting cancer.

So, if this is used as the parameter for studying breast cancer then it will limit Lorenzo's research as the women in groups 25-30 do not have cases of cancer.

Therefore, this strategy will be more time-consuming.
