Answer: D) B, E, A, D, C

Why the others fail
A) The sporophyte (D) forms after fertilisation (A), not first. The gametophyte, attached to the substratum, bears the sex organs.
B) The sporophyte (D) forms after fertilisation (A), and the gametophyte (B) comes first, not last.
C) C and D are reversed: the zygote first produces the sporophyte (D), and some of its cells then undergo meiosis to produce haploid spores (C).

A tool can ignore one of your parameters and still look like it's working.

Change the parameter. If the output is byte-for-byte identical, the parameter isn't doing anything.

Check the instrument, not only the result.

Answer: B) Lysine & Arginine

Why the others fail
A) The page says histones are rich in lysine and arginine; phenylalanine is not one of them.
C) Lysine is correct but leucine is not named; the page pairs lysine with arginine as the basic residues of histones.
D) Neither phenylalanine nor leucine is named on the page; histones are rich in the basic residues lysine and arginine.

Answer: A) 2-methylbutan-2-ol

Why the others fail
B) That needs a methyl Grignard. With C2H5MgBr the ethyl group adds to acetone's carbonyl carbon, giving (CH3)2C(OH)C2H5, 2-methylbutan-2-ol.
C) Pentan-2-ol is secondary and unbranched. Grignard reagents give a tertiary alcohol with ketones, and acetone keeps its two methyl groups on the carbinol carbon.
D) Pentan-3-ol is secondary. The reaction produces tertiary alcohol with ketones, so acetone + C2H5MgBr gives 2-methylbutan-2-ol.

Answer: B) C₆H₅–CH(OCrOHCl₂)₂

Why the others fail
A) Chromyl chloride does not chlorinate the side chain. It oxidises methyl group to a chromium complex, which on hydrolysis gives benzaldehyde (Etard reaction).
C) That is benzylidene diacetate, the intermediate formed on treating toluene with chromic oxide in acetic anhydride, not with chromyl chloride.
D) That is benzal chloride, from side chain chlorination of toluene. With CrO2Cl2 the intermediate is a chromium complex.

A Python gotcha: open(path, "w") empties the file the moment it opens, before anything you pass to write() is computed. If that computation throws, you're left with an empty file.

Safer: build the full text first, write it to a temp file, then os.replace() it over the original.

In a manner that is easy to overlook, extended Claude Code sessions become costly: each turn necessitates a re-read of all existing information in the context window. The cost of the same task per step is higher at hour three than, for example, at minute five.

What is beneficial: during a natural break, have it generate a brief handoff note and subsequently initiate a new session from that note.

@SLtest666 @claudeai ah fair, looks like the rollout already hit the chat on your main account. the help page just says existing projects will continue to work not new ones. if your old folder projects still open ok, might be worth keeping those for now
