Answer:
Since you said in the comment above that the underlined word is "random", I'd also say that the best replacement for it would be "inaccurate".
Explanation:
When we take some of the synonyms of random into consideration, we can conclude the the best replacement for it is the word "inaccurate":
- purposeless;
- unaimed;
- unplanned;
- incidental etc.
Inaccurate presents, among its synonyms, the following:
- careless;
- imprecise.
Something that has no purpose, that is not planned, is the same as something that has no care, no precision. Thus, we could replace random for inaccurate.
