In each of the questions below, a sentence is given with two portions marked in bold. Choose the best replacement (if needed) for the highlighted portion to make the sentence meaningfully and grammatically correct. Well-ordered large-pore anode aluminum oxide membranes were one-step prepared in water-deficient electrolytes using ethanol as main insolvent. Correct Answer Anodic, solvent
The sentence is related to science. Anode is a term related science. It means ''the positively charged electrode by which the electrons leave an electrical device.'' But here we can't use this noun form. Because here we are not focusing on the anode but the membrane. In the first blank, we need the adjective ''anodic'' and in the second blank we need the word ''solvent.'' Solvent means ''able to dissolve other substances.'' Hence, option 2 is the correct answer.
Peroxide: a compound containing two oxygen atoms bonded together in its molecule or as the anion
observant: quick to notice or perceive things.
Electrode: a conductor through which electricity enters or leaves an object, substance, or region.
ordinance: an authoritative order.
