Explanation
The correct answer is "without." This is because the word "without" is used to indicate the absence or lack of something. It is often used to express the idea of not having or not using something. In this context, the word "without" is the most appropriate choice as it aligns with the meanings of the other options and accurately represents the concept of being without something.

For example, in words like "advance" or "adhere," the prefix "ad-" suggests moving forward or sticking to something. It can also imply proximity or closeness to a particular location or object. Therefore, the correct answer is "to, toward, or near."

Explanation
The prefix "ante-" means "before". It is used to indicate something that happens or exists before a certain event or time. For example, "antebellum" means "before the war" and "ante meridiem" means "before noon". Therefore, the correct answer is "before".

Explanation
The prefix "anti-" or "contra-" indicates opposition or being against something. Therefore, when combined with the word "upon," it suggests a sense of being opposed to or against something. The other options, such as "outside," "fight," and "later," do not convey the same meaning of opposition or being against.
