Final answer:
Algeria's government attempts to improve the economy through diversification, encouraging investment, and enhancing transaction systems and social services, rather than increasing military size or restrictions.
Step-by-step explanation:
The question regarding how Algeria's government has worked to better its economy touches upon various policy changes and developments that a country might undertake for economic improvement. While the question offers multiple choice answers, to provide context, Algeria's economic reforms have often involved attempts to diversify the economy beyond oil and gas production, encouragement of foreign and domestic investment, and improving the transaction system to facilitate easier and more effective commerce. Moreover, improvements in social services can also contribute towards economic betterment by creating a more stable and capable workforce. However, increasing the size of its military or increasing restrictions does not directly relate to improving the economy and can often have a contrary effect. It should be noted that while these actions can be beneficial, Algeria's government has also faced challenges such as bureaucracy and the need for reforms in other sectors, including the financial system and public sector enterprises.
