The correct words for the blanks are (i) difficult, (ii) relatively simple, and (iii) exceptional.
Breakdown of the Blanks
- Blank (i): C. difficult
The passage begins by stating that the research is "surprisingly" something, and then it immediately provides a reason for this quality: "estimation... is surprisingly hard." This implies the research is generally challenging. Therefore, difficult is the best fit.
- Blank (ii): E. relatively simple
The sentence describes the conditions in Shetland, an example where estimating how much otters use an area is easy. Otters are active during the day and have clear markings, making it possible to identify individuals. The phrase relatively simple perfectly captures the ease of research in this specific location.
- Blank (iii): I. exceptional
The word "However" signals a contrast between the situation in Shetland and the general conditions of the field. The conditions in Shetland, which make the research relatively simple, are not the norm. Therefore, these conditions are exceptional, meaning they are unusual or not typical of most research environments.
