The above Multiple Choice Question (MCQ) has been selected from Everyday Science Category. Everyday Science MCQs are sometimes called EDS MCQs. We try our level best to provide you with error-free questions/MCQs. However, in case you find any mistake in the MCQs, feel free to contact us for its correction. It is pertinent to mention here that the Everyday Science MCQs have their own importance and are repeatedly included in different examinations. Some leading testing agencies / organizations such as Central Superior Service (CSS), Federal Public Service Commission (FPSC), Punjab Public Service Commission (PPSC), Khyber Pakhtunkhwa Public Service Commission (KPPSC), Balochistan Public Service Commission (BPSC), Sindh Public Service Commission (SPSC), National Testing Services (NTS), Open Testing Services (OTS), Universal Testing Services (UTS), Pakistan Testing Services (PTS), Central Testing Services (CTS), Allied Testing Services (ATS), Educational Testing and Evaluation Agency (ETEA) etc. used to include MCQs from Everyday Science category. The Everyday Science MCQs are not only beneficial for the Job seekers (Jobs MCQs) but also helpful for the students who are trying to seek admissions in educational institutions / universities of their choice preceded by appearing in their Entry Test Exams (Entry Test MCQs). These tests include UET ECAT (is a test based on Physics, Mathematics, Chemistry and English), MDCAT (is a mandatory admission test for medical and dental college), SAT (include SAT-I “a reasoning test” and SAT-II “a subject test”), GRE (it is also known as Graduate Record Examination comprises two types of tests, the GRE subject (subjects include Physics, Biology, Chemistry, Psychology and English Literature) and the GRE general test (Analytical Writing Assessment, Verbal Reasoning and Quantitative Reasoning), LCAT (LUMS common admissions test is mandatory for candidates seeking admission at LUMS), NUST Entry Test, COMSATS-NTS Test, LAT (Law Admissions Test is a mandatory pre-admission test to get admission in LLB 5 years program) etc. In addition, the information contained in MCQs is equally beneficial for the those who are fond of gathering and enhancing their knowledge.
