Not sure that I quite understand the implication here (the English is not really grammatical or idiomatic (at least not in UK English), so it's a bit hard to be sure of what option in meaning was really being aimed for)
Is it like "I have a sense of these things" (some degree of awareness and understanding)
or like more like "I have a nose for these things" (a flair for reading/deciphering or sniffing them out) ?
I put "I have a feel for these things." Which Duo. marked wrong but I disagree. Anyhow it is a unfinished sentence that might be said if two or more people were talking about a know subject like how to find their way out of a forest and one says ... (insert the above sentence.)
