Excerpt from product review: battery chargers
steve dawson

1 with the growth of the green movement, more people are recycling and reusing products instead of purchasing new ones. this has led to a renewed interest in rechargeable batteries. the most common complaint about rechargeable batteries is poor performance. recharged batteries often fail to provide the same amount of power as new batteries. our researchers tested three rechargeable battery brands found in most local stores to determine which battery and charger combination provides the most energy.

how would a diary entry comparing battery chargers differ from this article?
a) the diary entry would contain fewer pictures.
b) the diary entry would have a more casual tone.
c) the diary entry would target a specific audience.
d) the diary entry would contain more scientific data.

B). The diary entry would have a more casual tone.

Explanation:

A diary entry is elucidated as the informal journal where an individual expresses the significant events took place in his/her life along with a blend of personal thoughts, opinions, or feelings associated to it while an article is exemplified as an objective yet a formal expression of a specific event or subject for general interest.

As per the question, a diary entry would differ in tone and expression from the given article while comparing the battery chargers. A 'diary entry would adopt a more casual and personal tone' to describe them along with a touch of author's personal thoughts or feelings(through the use of more descriptive words) about these chargers which is contradictory to the formal and objective tone adopted in the article('The most common complaint about rechargeable batteries is poor performance') to present a factual description for general interest. Thus, option B is the correct answer.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
