When a glass rod is rubbed with a silk cloth, it becomes positively charged. To determine which items it would attract, we need to consider the properties of the objects in the context of electric charge.

1. **Neutral Objects**: A positively charged object will attract neutral objects because they will be induced to have a slight negative charge on the side nearest to the positively charged object. This means any neutral item would be attracted.

2. **Negatively Charged Objects**: A positively charged object will also attract any negatively charged items because opposite charges attract.

3. **Positively Charged Objects**: Positively charged items will repel the positively charged glass rod, meaning it will not be attracted to them.

Based on this reasoning:

- If **balloon 1** is negatively charged, it would be attracted by the positively charged glass rod.
- If **balloon 2** is neutral or positively charged, it would either be attracted or repelled depending on its charge status.
- **Plastic sheet 1** and **plastic sheet 2** need to be assessed similarly based on their charges.

Given this information, if we are looking for items that would be attracted to the positively charged glass rod:

- If **balloon 1** is negatively charged, it would be attracted.
- If **balloon 2** is neutral, it would be attracted.
- If **plastic sheet 1** and **plastic sheet 2** are neutral or negatively charged, they too would be attracted.

Without the actual images or specific details of the charge of each item, we can reasonably say that if balloon 1 is negatively charged and/or the other items are neutral, those would be the ones attracted to the positively charged glass rod.

Based on typical assignment structures, the correct answers may include:

**A. balloon 1** (if it is negatively charged)
**B. balloon 2** (if it is neutral)
**C. plastic sheet 1** (if it is neutral)
**D. plastic sheet 2** (if it is neutral)

Thus the answer could be **E. balloon 1 and balloon 2** or more generally, all non-positively charged items would be included based on their charges.
