My research career is taking ____ because my professor asked me to write a paper for an international journal.

• A. Shape
• B. Form
• C. Turn
• D. Course

Answer: (A)

The idea being tested is how we use the verb take with a noun to express development. When we say something is taking shape, we mean it is beginning to develop into a clear, recognizable form. In this sentence, your research career is starting to become more real and defined as you take steps like writing a paper for an international journal. That makes taking shape the natural choice because it conveys progress and maturation of something abstract like a career.

Taking form is a valid expression in some contexts, but it isn’t as commonly used for abstract developments like a career; it often sounds more physical or less fixed. Turning or changing direction would be suggested by a phrase like taking a turn, which doesn’t fit the idea of gradual growth here. Taking course would imply following a study program, which isn’t the intended meaning in this sentence.
