The image contains two flowcharts labeled "c." and "d.", each depicting a network of nodes connected by directed arrows. Here’s a detailed description of both diagrams:### Diagram C:- **Nodes and Values:** - Node S connects to Nodes A and C. - Node A connects to Nodes B, C, E, and F, with a value of 1. - Node B connects to Node D, with a value of 4. - Node C connects to Node F, with a value of 5. - Node D has a value of 4. - Node E connects to Node G, with a value of 1. - Node F connects to Nodes E and G, with a value of 7. - Node G connects to Node J, with a value of 3. - Node H connects to Node J, with a value of 1. - Node J connects to Node F, with a value of 6.### Diagram D:- **Nodes and Values:** - Node S connects to Nodes A and C. - Node A connects to Nodes B, C, E, and F, with a value of 1. - Node B connects to Node D, with a value of 4. - Node C connects to Node F, with a value of 5. - Node D has a value of 4. - Node E connects to Node G, with a value of 1. - Node F connects to Nodes E and G, with a value of 7. - Node G connects to Node J, with a value of 3. - Node H connects to Node J, with a value of 1. - Node J connects to Node F, with a value of 6.### Shared Characteristics:- Both diagrams start at Node S.- The graphs are directed, meaning the arrows indicate the direction of flow from one node to another.- Numerical values are associated with each connection, representing weights or distances.### Differences:While the diagrams appear structurally similar with identical nodes and connections, the main difference lies in visual presentation without altering the structure.These diagrams could represent various network models, such as transportation routes, project scheduling, or data flow systems, where the goal is often to find the shortest path or the most efficient route from a starting point to an endpoint. ### Project Data for Installing a New Server at Northland Pines High School#### Activity Details:- **A**: Time = 1 day, Predecessor = None- **B**: Time = 4 days, Predecessor = A- **C**: Time = 5 days, Predecessor = A- **D**: Time = 4 days, Predecessor = B- **E**: Time = 1 day, Predecessor = B- **F**: Time = 7 days, Predecessors = B, C- **G**: Time = 3 days, Predecessors = D, E- **H**: Time = 2 days, Predecessor = F- **I**: Time = 3 days, Predecessor = F- **J**: Time = 6 days, Predecessors = G, H, I#### Task:- **Choose the correct network diagram:**Diagram **A**:- Starts with Activity A.- Activities B and C follow A.- Activity D follows B.- Activity E follows B.- Activity F follows B and C.- Activities G follows D and E.- Activities H and I follow F.- Activity J follows G, H, and I.Diagram **B**:- Incorrect as the paths and connections between activities don't align with the dependencies.To solve: Select **Diagram A**, as it accurately represents the dependencies outlined in the table.

CASE - CAPACITY BUILDING PROJECT AIMS TO INCREASE YOUTH INVOLVEMENT IN SUSTAINABLE DEVELOPMENT Basseterre, St. Kitts, April 29, 2021 (SKNIS): St. Kitts and Nevis Youth Ambassador Corps officially launched a new project on Wednesday (April 28, 2021) designed to increase the contributions of young people to the sustainable development of the twin-island Federation. The initiative, dubbed the Youth Capacity Building Small Grants Project on Youth in Sustainable Development, will build the capacity and practical skills of young people to design, implement, and monitor interventions relevant to the social, economic, and sustainable development of youth and their communities. The project is geared towards members of youth groups specifically. It is spearheaded by the national youth ambassador corps in collaboration with the GEF Small Grants Programme (SGP), and the Departments of Youth in St. Kitts, and Nevis. The Small Grants Project is funding the initiative to the tune of US$49,970.00. SGP…
