From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences. 

I have made remarkable progress ______ learning French.

Answer Details

The best option to complete the sentence is "in". "In" is the most appropriate preposition to use when referring to progress made in learning a language. It indicates the area or field in which the progress was made. So, saying "I have made remarkable progress in learning French" means that the speaker has made significant strides in the process of acquiring knowledge of the French language. On the other hand, "by" is often used to indicate the means or method by which something was achieved, for example, "I made remarkable progress by practicing every day". "At" can be used to describe a level of proficiency, for instance, "I am good at speaking French". Lastly, "for" would not fit in the context of progress in learning a language.
