### Project Management Exercise: Installing a New Sewer at Northland Pines High School

Consider the following data for a project to install a new sewer at Northland Pines High School:

| Activity | Activity Time (days) | Immediate Predecessor(s) |
|----------|----------------------|--------------------------|
| A        | 2                    | -                        |
| B        | 4                    | A                        |
| C        | 5                    | A                        |
| D        | 2                    | B, C                     |
| E        | 3                    | B, C                     |
| F        | 8                    | D, E                     |
| G        | 1                    | F                        |
| H        | 5                    | F                        |
| I        | 4                    | G, H                     |
| J        | 7                    | G, H, I                  |

#### a. Choose the correct network diagram below:

![Option A](placeholder-for-image) ![Option B](placeholder-for-image)

---

For this task, the student needs to analyze and select the correct network diagram that represents the activities and their dependencies as per the table. The diagrams labeled "Option A" and "Option B" will provide visual workflows showing how each task is connected based on its immediate predecessors.

Please select the appropriate option that accurately reflects the project schedule and the logical sequence of the activities.

The image shows a section from a digital educational quiz related to organic chemistry, specifically focusing on molecular structures and their nomenclature.

The image contains four labeled options (A, B, C, D) depicting four different molecular structures. Each structure represents a different compound with variations in the arrangement of atoms and bonds.

### Description of the Molecular Structures:

1. **Option A:**
   - The structure appears to be a carbon ring with six carbon atoms. Each carbon atom is bonded to a hydrogen atom.
   - Two opposite carbon atoms have additional substituents, likely alkyl groups.

2. **Option B:**
   - This structure is similar to the structure in Option A but with different substituents.
   - It features a carbon ring with six carbon atoms as well, each bonded to a hydrogen atom.
   - Three of the carbons have different substituents attached.

3. **Option C:**
   - Somewhat differing from the structures in Options A and B, this ring is more complex.
   - It consists of a carbon ring with six atoms, with each carbon atom bonded to a hydrogen atom and specific substituents attached at certain positions.

4. **Option D:**
   - This option shows the same six-carbon ring as the previous structures, but the attachment points of the substituents differ.
   - It features a simpler arrangement, with fewer substituents attached compared to Options B and C.

### Graphs/Diagrams:

- **Visualization Tools:**
  - Each molecular structure is accompanied by icons for zooming in/out, allowing closer examination of the structures.
  
### Instructions:

- Participants are likely required to identify or match these molecular structures based on given criteria not visible in the image.
- There is an option to "Clear All" selections, indicating it is a quiz where students need to select the correct option before submitting their answers.

This content is typically used for instructional purposes in understanding molecular structures and their variations in organic chemistry education.
