Answer:
I don’t doubt the effectiveness of this new gadget, but we simply don’t have the money to buy it.
Explanation:
The word ”effectiveness” means a degree to which something is successful in making a result that is desired. In other words, something with effectiveness is something that successfully produces a result that a person wants/desires. It makes a desired change/effect for the person using it. The effect is rooted within the word too, so that is why it’s the appropriate word to use.
What is your question, you have not put anything?
