For the first question regarding the correct match between ideas related to the formation of the universe, the accurate response is:
- **structure forming in the early universe — dark matter**
This option is correct because dark matter plays a crucial role in the formation of structures in the universe by providing the necessary gravitational influence.
For the second question regarding the definition of dark energy, the most accurate response would be:
- **Energy that humans cannot observe directly**
This option is correct because dark energy is a theoretical form of energy that is thought to drive the accelerated expansion of the universe, but it does not emit light or radiation, making it difficult to observe directly.
