Answer (4)
A developing country might only have primary and secondary economic activities because the economy is not developed enough to engage in other levels of economic activities. Primary activities are the extraction or cultivation of natural resources and secondary activities are the manufacturing of finished goods. A developing economy may have only reached development of these sectors because of inefficiencies and weaknesses in the economy that it has not overcome through development yet.
The correct explanation for why developing countries might have only primary and secondary economic activities is due to their stage of economic development and the historical progression of economic activities.
Economic activities are typically categorized into three sectors: primary, secondary, and tertiary. Primary activities involve the extraction of raw materials and natural resources, such as agriculture, forestry, fishing, and mining. Secondary activities include manufacturing and construction, where raw materials are processed and turned into finished goods. Tertiary activities, also known as the service sector, involve the provision of services rather than goods.
Developing countries often have economies that are heavily reliant on primary and secondary sectors for several reasons:
Resource Endowment: Many developing countries are rich in natural resources and have a comparative advantage in primary sector activities. This leads to a focus on agriculture, mining, and other resource extraction industries.
2. Economic History and Development: Historically, countries tend to develop their economies by first exploiting natural resources (primary), then developing industries to process these materials (secondary), and finally moving towards a service-based economy (tertiary) as incomes rise and the demand for services increases.
3. Capital and Technology: The primary and secondary sectors are often more capital-intensive and require less skilled labor compared to the tertiary sector. Developing countries may lack the advanced technology and capital necessary to develop a large tertiary sector quickly.
4. Labor Market: The labor force in developing countries may not have the education or skills required for a large service sector. As education levels improve and the workforce becomes more skilled, the service sector can expand.
5. Economic Structure and Income Levels: As countries develop and income levels rise, there is a natural shift towards the tertiary sector. People start to demand more services such as healthcare, education, finance, and entertainment. Developing countries are often at an earlier stage of this economic transition.
6. Global Market Dynamics: Developing countries may also focus on primary and secondary activities due to their integration into the global economy, where they often serve as suppliers of raw materials and low-cost manufactured goods to more developed countries.
Government Policies: Sometimes, government policies can also influence the economic structure. Subsidies, tariffs, and other forms of support may be directed towards agriculture and industry, while the service sector remains underdeveloped due to less favorable policies.
In summary, the concentration of primary and secondary economic activities in developing countries is a reflection of their current stage of economic development, resource endowments, labor market conditions, technological capabilities, and historical economic trajectories. As these countries continue to develop, it is common for the tertiary sector to grow in importance, leading to a more diversified economy.
Developing countries primarily engage in primary and secondary economic activities due to limited economic diversification, resource availability, investment limitations, insufficient education levels, and infrastructure challenges. These factors restrict their ability to expand into more advanced service sectors. As a result, their economies often focus on simple agriculture and basic manufacturing.

Jawaban:Kegiatan pembelajaran yang direncanakan guru tersebut bertujuan untuk: - Menemukan hubungan antara luas segitiga dan luas persegi panjang. Guru membimbing siswa untuk melihat bagaimana segitiga terbentuk dari setengah persegi panjang, sehingga mereka dapat menyimpulkan bahwa luas segitiga adalah setengah dari luas persegi panjang.- Memahami konsep luas segitiga. Dengan mengamati dan membandingkan, siswa akan lebih memahami bagaimana luas segitiga dihitung dan faktor-faktor apa saja yang mempengaruhinya (alas dan tinggi).- Mengembangkan kemampuan pemecahan masalah. Siswa diajak untuk menemukan tinggi segitiga dan membandingkan luas, yang melatih kemampuan mereka dalam memecahkan masalah matematika.- Meningkatkan pemahaman visual dan konkret. Penggunaan gambar dan benda konkret membantu siswa untuk lebih mudah memahami konsep abstrak tentang luas.- Mengaktifkan siswa dalam pembelajaran. Siswa tidak hanya menerima informasi, tetapi juga aktif mengamati, menemukan, dan membandingkan, sehingga pembelajaran menjadi lebih bermakna.
