allery'କିଛି S ହେଉଛି P' ଏହା ନିଶ୍ଚିତ କରେ କି ଯେ 'କିଛି S, P ନୁହେଁ' ସତ୍ୟ ଅଟେ?
Aକେବଳ ଯେତେବେଳେ S ଖାଲି ଥାଏ
Bହଁ, ପ୍ରତ୍ୟେକ କ୍ଷେତ୍ରରେ
Cନା, ଆବଶ୍ୟକ ଭାବେ ନୁହେଁ
Dକେବଳ ଯେତେବେଳେ P ଖାଲି ଥାଏ
Answer & Solution
Correct answer: C. ନା, ଆବଶ୍ୟକ ଭାବେ ନୁହେଁ
ଯେହେତୁ 'କିଛି' ମଧ୍ୟରେ 'ସମସ୍ତ' ଅନ୍ତର୍ଭୁକ୍ତ ହୋଇପାରେ, ପ୍ରତ୍ୟେକ S, P ହୋଇପାରେ ଏବଂ ସେତେବେଳେ କୌଣସି S, P ବାହାରେ ରହିବ ନାହିଁ।
