Question: A woodpecker’s brain is specially protected from large accelerations by tendon-like attachments inside the skull.

Question: Consider our start-up company, which is looking to develop a mobile application for monitoring sleep disruptions (e.g., snoring, restless sleep) using a user’s phone microphone. Users will be prompted to complete a mindfulness questionnaire on their phones each morning and night, allowing them to correlate sleep disruptions and mood. Users can also view reports on a website.

Question: Consider the case of global environmental problems that spill across international borders as a prisoner’s dilemma of the sort studied in [Monopolistic Competition and Oligopoly](10-introduction-to-monopolistic- competition-and-oligopoly) .

If one country decides to protect the environment, there is a benefit of 16, but the benefit is divided equally between the two countries. If both countries decide to protect the environment, there is a benefit of 32, which is divided equally between the two countries.    A. In [Table 12.10](12-self-check-questions#Table_12_15), fill in the costs, benefits, and total payoffs to the countries of the following decisions. Explain why, without some international agreement, they are likely to end up with neither country acting to protect the environment.  | **Country B**   ---|---   Protect | Not Protect   **Country A** | Protect |  |    Not Protect |  |    Table 12.10
