This is how to solve the problem:
We know that the growth rate is constant for both species of plants. So we can say that the height is a linear function of the number of days since d = 0.
Assumption (1 month = 30 days)
Species A:
Growth rate = 2 cm/month = 2/30 = 1/15 cm/day
Height on day d = 0: 12 cm
Height: H(d) = 12 + d/15
Species B:
Growth rate = 3 cm/month = 3/30 = 1/10 cm/day
Height on day d = 0: 10 cm
Height: H(d) = 10 + d/10
D. Because the rest dont make sense
I think the reason why the summary need to be revised is : C. the summary lacks transitions that connect ideas
For example, we need to add transition between -enkai wanted to save his cattle- and -He grew a tree that bridged the sky and the earth-
Hey There!
The answer would be D, rising action.
It causes a little confusion to have that "Blank Space" right after the the main verb "expect" because we cannot be sure that it represents that a blank or a space is that follows, or that Blank Space is used as a noun.
To answer this question I will assume that blank space represents that a line goes there to be filled.
By doing so, the correct sentence would be:
Joel and Lucy expect _their_ Halloween party to be really scary!
So the final answer is:
Their
The possessive third person plural pronoun is the best option.
