<span>The correct answer is A. the results of a scientific study would be the most effective evidence. Thoughts and opinions are not valid for scientific studies because they are based on emotions and personal values. Ethics also have a problematic effect on science because values and morals are often different from society to society.</span>
A. is wrong because (could'nt) is not the proper way to write the contraction for 'could not' it should be 'couldn't', also there is no need for the apostrophe after the word, yours it already possessive without the apostrophe.
B. is wrong because 'couldnt' is not the correct way to write the contraction for 'could not', it's couldn't.
C. She couldn't remember which suitcase was your's. is wrong because you don't need the apostrophe in your's because it possessive is, yours.
The sentence that contains no errors is D. She couldn't remember which suitcase was yours.
Hope this helps. :)
Hi there! I feel that C.) would be the best answer for this question. Fighting in a war wouldn't show that you value the culture of your homeland, like shown in answer A.). B and D seem irrelevant to the question at hand, and since the language of a country relates directly to the culture and answer C.) shows that Juhan values it, it'd be safest to go with that answer.
