Answer:
a) The research team is taking measurements of Jonathan's height and weight to assess his growth
Step-by-step explanation:
Anthropometry is a branch of anthropology that studies the measurements and dimensions of the various parts of the human body. Based on this concept, the term anthropometric data was created to refer to the activity where a group of nurses (or other professionals) take measurements of some parts of the body, such as height and weight, for example. For this reason, in the case described in the question above, nurses should reassure Jonathan's parents that the research team will measure Jonathan's height and weight to assess his growth.
