Perfective Active and Passive. FR CAP XXIII

I appear to have two different editions of the LL Teacher’s Materials and LL Exercitia Latina which I suspect accounts for my wrong answers - but may not!

Exercitia Latina - CAP XXIII - Ex. 1 - Perfect active and passive exercise.

(Teacher’s Materials):

  1. Magister epistulam [scripsit] = Epistula a magistro [scripta] est.
  2. Magister epistulam ad Iulium [misit] = Epistula ad Iulium [missus] est a magistro.
  3. Iulius epistulam [legit] = Epistula a Iulio [lectae] est.

No problem with No. 1.
No. 2. My answer: “missa”.
No. 5. My answer: “lecta”.

Am I missing something?

No, you are not missing anything. Your answers are right.

Multas gratias tibi ago.
