The growth of suburbs led to two important developments: The growth of malls and the birth of the "car culture".

Step 1: Understanding the question The question asks for two developments that were a result of the growth of suburbs.

Step 2: Analyzing the options A. The growth of rural areas and cities - This is not correct because the growth of suburbs usually leads to a decrease in rural areas as more land is developed for housing. Also, while cities may grow in population due to suburban growth, it's not a direct result. B. The growth of malls and supermarkets - This is partially correct. The growth of suburbs did lead to the growth of malls as more retail space was needed to cater to the increased population. However, supermarkets are not a direct result of suburban growth. C. The growth of malls and the growth of mass-produced apartments in cities - This is partially correct. As mentioned before, the growth of suburbs did lead to the growth of malls. However, mass-produced apartments in cities are not a direct result of suburban growth. D. The growth of cities and the birth of the "car culture" - This is correct. The growth of suburbs led to the growth of cities as more people moved to the suburbs and commuted to the city for work. This also led to the birth of the "car culture" as people needed cars to commute from the suburbs to the city.

Step 3: Choosing the correct answer The correct answer is D. The growth of cities and the birth of the "car culture".
