Observational methods, case-study methods and survey methods.
Observational Method
With the observational method (sometimes referred to as field observation) animal and human behavior is closely observed. There are two main categories of the observational method — naturalistic observation and laboratory observation.
Case Study Method
Case study research involves an in-depth study of an individual or group of indviduals. Case studies often lead to testable hypotheses and allow us to study rare phenomena. Case studies should not be used to determine cause and effect, and they have limited use for making accurate predictions.
Survey Method
In survey method research, participants answer questions administered through interviews or questionnaires. After participants answer the questions, researchers describe the responses given. In order for the survey to be both reliable and valid it is important that the questions are constructed properly. Questions should be written so they are clear and easy to comprehend.

These are the two correct answer choices:
A The modern map includes A land masses the ancient map does not show.
D The modern map shows the shapes of land masses more accurately than the ancient map.
Explanation:
The two answer choices above are closely related. Ancient maps often were less detailed than modern maps because ancient cartographers, geographers, and sailors had less technical tools to craft their maps.
Ancient maps were usually partial maps as well: they only showed specific geographical areas, while leaving other areas uncovered, simply because the authors did not even know what territories lied beyond certain geographical limits. For examples, the Ancient Greeks did not know of Subsaharan Africa, so their maps did not give account of that part of the world.

A cross-sectional study is a type of study design that involves subjects who vary in the variable of interest such as age but have a common characteristics and observations are made at a single point in time.
In the scenario from the question, the variable of interest is most likely the effect of varying age groups on personal health. The variable of interest, age group varies but the population has a common characteristic which is that they are Americans and the study is done at a particular time and not spread out as in cohort studies. This is an example of a cross-sectional study.
