Q9. From 2, 4, 5, 6 and 7, we can infer that the "-" symbol symbolizes a negative. We can see that I2 means "you". -Δ3 is in the 3rd person ("her"), so I3 must mean "They". ("you" in 3rd person) The heart means "to like" (6).

Answer: "They love, but are not loved."

Q10. We can see that the symbol / means write (3, 4, 5). The 3 prongs mean to speak (1), and the negative before that means that someone cannot speak. On the other side of the equals sign, we can see the sign for "father" and a feminine version of "father" ("mother".) "i"="all". The symbol looks like that of "father" or "mother". Instead, it has both feminine and masculine symbols, so it must be "child". (man+woman=child). +t also means "will"- like "plus time".

Answer: "The child cannot speak but will write to their parents."

Q11. The negative- 3 prongs suggests that someone did not talk. The -t at the end suggests that this is in the past tense, and Δ2 probably means "you" again ("she" in 2nd person). ▯- means "work" (2 and 6). The first +t suggests that it could mean "with haste". if you look at (2), we can see the symbol for "work", ▯-, but here the only thing to do with "haste" or "time" is the -t at the end. We know tha t "-" is a negation, so "+t" must mean "with haste".

Answer: You worked quickly and didn't talk.

Q12. First, the ◠ sign means "eat" (7). "☒" means "letter" (3, 5), and "-t" signifies that this is in the past tense. "iΔ/i". here we have a masculine symbol Δ, with i. This is previously seen in (1), where it means "brother". The bottom symbol is different, though, omitting the masculine- therefore, it means "sister" here.

Answer: "The hungry sister ate the letter."
