The correct answer is option 'B' - The space suits they wore were inconvenient.

Explanation:

Handling construction materials in space can indeed be challenging, but it is not mentioned in the given options as the reason for the difficulty of constructing the space station. Similarly, there is no information provided about limited time or the size of the space station being the main challenges faced by Svens team.

However, the option 'B' states that the space suits they wore were inconvenient, which seems to be the most plausible explanation for the difficulty in constructing the space station. Let's explore this further:

1. Importance of Space Suits:
Space suits are essential for astronauts to survive and work in the harsh conditions of space. They provide a life-support system, protect against extreme temperatures, and maintain pressure for breathing. Without space suits, it would be impossible for astronauts to work outside the spacecraft or space station.

2. Inconvenience of Space Suits:
a. Bulky and Restrictive: Space suits are bulky and restrict the free movement of the astronauts. The suits are pressurized to provide a suitable environment for astronauts, but this makes them stiff and difficult to maneuver in.

b. Limited Mobility: Due to their bulkiness, space suits limit the range of motion of astronauts. Simple tasks that are easy to perform on Earth become much more challenging in space suits.

c. Dexterity Issues: The gloves of space suits are thick and rigid, making it difficult to perform precise tasks that require fine motor skills. This can make construction work, which often requires intricate maneuvers, more challenging.

d. Communication Difficulties: Space suits also pose communication challenges. The bulky helmets and the limited range of motion restrict verbal and non-verbal communication between astronauts.

3. Impact on Construction Work:
The inconvenience of space suits can significantly impact the construction work on a space station. The astronauts may face difficulties in handling tools, manipulating objects, and maintaining balance while wearing these suits. Even simple tasks like fastening bolts or connecting components may become time-consuming and require extra effort.

In conclusion, the difficulties faced by Svens team in constructing the space station were primarily due to the inconvenience of the space suits they wore. The bulky, restrictive nature of the suits limited their mobility, dexterity, and communication, making construction work more challenging.
