Language is most objective when based upon
a; opinion
b; beliefs
c; thoughts
d; evidence

(D) Evidence

Explanation:

The language is objective when it is based upon the evidences as the objective language is the type of language which is accurate and fair. The objective language avoid all the kinds of bias and the exaggeration.

 The language is more objective when it is based on the evidences as the real evidences justify the given facts true that makes the situation more efficient and true. The evidences support all the true proofs about the given situation and facts.

Therefore, Option (D) is correct.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
