## Answer

In an intriguing development in astro-botany, researchers are exploring the potential of watermeal, the world's smallest flowering plant, in hypergravity conditions. This research **aims** to assess its suitability as a sustainable food **source** and oxygen producer for astronauts. Conducted in environments mimicking space conditions, the study explores how watermeal grows and thrives under increased gravity. The plant's small size and rapid growth rate make it an **ideal** candidate for space cultivation. If **successful** , watermeal could become a vital component of life-support systems in long-duration space missions, providing astronauts with a renewable source of food and oxygen. This research not only contributes to the advancement of space exploration but also opens up new possibilities in understanding plant biology **under** extreme conditions. It can also offer insights into how plants might adapt to changing environments on Earth, particularly in response to climate change.

## Explanation

Blank 4 follows "If" with no subject, so you need a short adjective form. "If successful" means "if it is successful." "Succeeds" would need a subject, and the other options are not real words. In blank 2, "a food source" means a supply of food. "Root" and "cause" do not pair with "food" here.

## Hints

- Look for clues in the surrounding words, such as prepositions or articles, that dictate the form of the missing word.
- Consider the overall purpose of the study mentioned in the text to identify the most logical vocabulary choice.
