Final answer:
Arguments for tariffs and export subsidies vary in validity: Argument D about semiconductors may support protection due to national security concerns, while others, like Argument B regarding Chilean fruit imports, highlight the benefits of free trade rather than justifying tariffs.
Step-by-step explanation:
When examining arguments for tariffs and export subsidies, it is important to analyze each on merit and in context:
- Argument A does not provide a valid reasoning for tariffs or export subsidies. The assumption that importing more oil will drive up global prices does not account for the complexities of the oil market and how prices are determined on a global scale.
- Argument B, regarding the import of off-season fruits from Chile, shows a benefit of imports, as they help reduce the prices of these goods, potentially to the consumers' advantage. This does not support an argument for tariffs; instead, it highlights the benefits of free trade.
- Argument C suggests that farm exports boost incomes not only for farmers but also for those related to the farm sector. While this highlights a benefit of exports, it does not necessarily justify subsidies unless a spillover effect to the broader economy can be clearly shown.
- Argument D implies a national security and strategic interest in producing semiconductors domestically. This can be a valid argument for tariffs and subsidies if it's demonstrated that reliance on foreign chips could impair critical industries.
- Argument E points out the job losses in the timber industry due to falling prices. This may support the use of tariffs or subsidies if it is to protect jobs, but it should be balanced against the potentially higher costs for consumers and other industries that use timber.
In conclusion, not all arguments presented are equally valid, and they hi-nge upon factors such as national security, economic impact, and the balance between consumer and producer interests.
