   A miner with a single GPU wants to earn a steady income but has a low hash rate. They are considering joining a mining pool. What is the primary benefit of joining a pool for this miner?

   • AThe pool combines hash power from many miners, increasing the chance of earning rewards, which are then distributed proportionally
   • BThe pool guarantees a fixed daily income regardless of network difficulty
   • CThe pool eliminates the need for mining software and hardware configuration
   • DThe pool reduces the miner's electricity costs by optimizing hardware settings

   A mining company is located in a region with a high percentage of coal-based electricity. They are under pressure from stakeholders to reduce their carbon footprint. They are considering three options: (1) purchase carbon offsets, (2) relocate to a region with renewable energy, or (3) switch to a PoS-based cryptocurrency. Which option most directly reduces the company's actual carbon emissions?

   • AUse more efficient ASIC miners to reduce energy consumption per hash
   • BPurchase carbon offsets, as this neutralizes their emissions without operational changes
   • CRelocate to a region with renewable energy, as this directly reduces the carbon intensity of their mining operations
   • DSwitch to a PoS-based cryptocurrency, as this eliminates the need for mining hardware entirely

   A miner is considering whether to mine blocks with empty blocks or include pending transactions. The miner is part of a pool and wants to maximize personal revenue. Which strategy is generally more profitable?

   • AMine empty blocks to reduce the risk of including invalid transactions.
   • BInclude only high-fee transactions to maximize fee revenue per block.
   • CMine empty blocks to reduce the time needed to validate transactions.
   • DInclude pending transactions to earn transaction fees in addition to the block reward.
