can you please help me with entity-relationship diagram problem, in the following question in the picture , name the tables and relationships , create correct relationship types , define attributes and meta data and correct optionalities, , identify primary and secondary keys, use naming conventions.

1. Each city is in a unique country. Data about cities include the name of the city and its population. Names of cities are unique within countries, but two cities in different countries may have the same name (and possibly even the same population). Information about a country includes its name and its head of state. You may assume no two countries have the same name. 2. Information about a consulate includes its name, which is unique (e.g., "consulate of the United States in Toronto") and its street address (which is unique within a city, but might not be unique among all consulates in different cities). 3. Cities and the country they are in are related by a relationship in. 4. 5. 6. Consulates and the city in which each is located are related by a relationship Location. There is no direct relationship between consulate and country. Each country represented by a consulate has a consul, who is represented only by a name. A subtle point is that occasionally, a consul will represent more than one country. For example, country A may not have diplomatic relations with country B, so A will ask country C to represent A's interests in country B at their own consulates. In that case, the consul for country A is actually a citizen of country C, and that person will likely not be the same as the consul for country C at the same consulate. While you might assume that a country would have at most one consulate in a given city, that is not always the case. For example, the US retains two consulates in Jerusalem 7
