2. What are these?
- They are goggles.
- They are trousers.
- They are scissors.

(Are the questions and answers all correct?)

Since "It" is in the answers for #1, I'd make these the answers:

It's a pair of googles.
It's a pair of trousers.
It's a pair of scissors.

1. To determine the correct answer to the question, "What's this?", you are provided with three possible options: goggles, trousers, and scissors. To find the correct answer, you can visually inspect the object being referred to. By using your perception and observation skills, you can analyze the characteristics of the object.

In this case, if the object being referred to has two separate lenses and an elastic band for securing it around the head, it is likely to be goggles. However, if it has long, tube-shaped fabric pieces that cover each leg and a waistband for securing it around the waist, it is more likely to be trousers. Lastly, if the object consists of two blades connected by a pivot point used for cutting, it is likely to be scissors.

Based on the descriptions provided, the correct answer for "What's this?" would be goggles if the object being referred to matches the characteristics described.

2. Similarly, to find the correct answer to the question, "What are these?", you need to visually inspect the objects being referred to. By observing their characteristics, you can match them to one of the provided options.

If multiple objects with two separate lenses and elastic bands are present, it would be correct to identify them as goggles. If you have more than one set of long, tube-shaped fabric pieces with waistbands, they can be identified as trousers. Lastly, if you have multiple objects consisting of two blades connected by a pivot point used for cutting, they can be identified as scissors.

Based on the descriptions, if you have multiple objects matching the characteristics described for each option, the correct answer for "What are these?" would be goggles if you have multiple sets of goggles, trousers if you have multiple pairs of trousers, and scissors if you have multiple pairs of scissors.

Please note that the correctness of the questions and answers depends on whether the objects being referred to match the characteristics described.
