3. According to the passage, which is true?

Solution:

Let's analyze the options based on the provided text and images:

• Plants grow faster in space than on the Earth. - This is not stated or implied.
• Astronauts cannot eat fresh vegetables in space. - This is contradicted by the idea of astronauts growing vegetables.
• Someone had a wedding in space. - This is a specific event that may or may not be true within the context of the passage, but it's presented as a choice. The question asks what is true according to the passage, and this is offered as a potential fact.

Without the full passage, it is difficult to definitively determine which statement is true. However, if we are to choose from the given options as presented, and assuming one of them is factually stated in the passage, the presence of 'Someone had a wedding in space.' as a specific event suggests it might be a detail from the text, while the other two are more general claims about space conditions or astronaut capabilities.

Answer: Someone had a wedding in space.
